In his excellent review of the United States department of (in)Justice's "Operation Chokepoint," Crypto Coin News writer "Caleb Chen" describes thirty industries being targeted by the Eric Holder administration of "Justice." The first thing to notice about the list is that these are activities that are lawful to operate in the United States.
Here is that very good article: http://www.cryptocoinsnews.com/news/dojs-operation-choke-point-driven-30-industries-bitcoin/2014/05/01
Here is a link from Caleb's article to a 2011 report from the United States federal deposit insurance corporation indicating their concerns for "high risk activities" in a slew of industries. http://www.fdic.gov/regulations/examinations/supervisory/insights/sisum11/managing.html
Now, if you like regulation, you can simply go to the FDIC site and pleasure yourself to the view of an all-powerful state running roughshod over undesirable business enterprises. You can imagine that of the roughly eight million business enterprises in the United States, only the very "bad" people who do unpleasant and harmful things (to your way of thinking, or, at least, to attorney general Holder's way of thinking) will be hassled and forced to stop accepting credit cards. But you might want to get the perspective of the presumed-state-enthusiast author Jason Oxman at "The Hill" who wrote on the same topic, recently, "If you’re thinking this is harmful to the flow of commerce, you’re right. Our nation’s payments infrastructure allows more than eight million U.S. merchants to accept credit and debit card payments." http://thehill.com/blogs/congress-blog/economy-budget/204174-operation-choke-point-harmful-to-flow-of-commerce
It is not merely harmful to the flow of commerce, it is harmful to everyone. The constitution for the United States which Americans like to pretend limits their government in various ways has much to say about what the government is and is not allowed to do. It says that the sanctity of contracts is to be upheld, that civil matters having more than $20 of value are to be adjudicated before a jury if the defendant prefers, that defendants are presumed innocent until proven guilty, and that everyone is entitled to due process of law, among a great many other protections that are evidently being ignored by the FDIC, the Department of (in)Justice, and the government. If the government can attack merchants in lawful industries such as ammunition sales, cable box equipment vendors, coin and stamp vendors, credit card services, credit repair services, dating services, debt consolidation services, pharmaceutical equipment vendors, escort services, firearms vendors, wealth development services, government grant services, home-based charities, lifetime guarantees, lifetime memberships, lottery sales, mailing lists, money transfer networks, online gambling, pay-day lending, pharmaceutical sales, adult film production and distribution, multi-level or network marketing sales systems (such as Amway, perhaps?), free press of unwholesome ideas such as racist rants, surveillance equipment vendors, telemarketing, tobacco vendors, and travel clubs, they can, will, and apparently do attack other merchants, individuals, and anyone they please.
Of the thirty types of business activity listed by the FDIC, only "Ponzi schemes" are evidently fraudulent by their nature. It is, of course, possible to operate a pharmaceutical sales company in the United States, with vendor representatives targeting your local doctor. You may even have seen these people in ill-fitting business attire waiting in the same waiting area when you or a family member have a doctor appointment. Whatever free samples, kickbacks, or incentives are allowed to the doctor by the pharmaceutical companies by the "regulated" healthcare industry in the several states is no doubt a matter of law. Maybe you'd even approve of those incentives, if your doctor bothered to ask you before writing a prescription on a pad generously provided by one of the Rx companies.
What does Operation Choke Point represent? It represents the egregore, the tendency of an organisation to take on a life of its own. While the term is also present in certain occult systems of thought (see https://en.wikipedia.org/wiki/Egregore for examples) my use of it here is in reference to the idea of a $3.5 trillion USA government completely run amok. Power mad regulators are prepared to use their oversight over the banking and payment processing industries to attack and intimidate merchants who have not been accused of any crime, who have not been convicted of any wrong-doing, and who are simply attempting to go about their lives.
You can say what you please about whether racist rants are suitable for reading, and you might be interested to know that I think racism is stupid, immoral, and bizarre. But you can't argue that the First Amendment to the constitution is supposed to protect freedom of the press, in that "congress shall make no law" abridging it. If you aren't willing to defend the freedom of people who write and think things you disagree with, who is going to defend your freedom? Evidently not the government under Obama and Holder, judging by their actual behaviour.
By presuming everyone guilty who sells ammunition or guns, the government is also, rather obviously, attacking the Second Amendment freedom to keep and bear arms. It is entirely understandable that state actors do not like ordinary people to have access to firearms. After all, the importance of being armed is widely document in political theory. Machiavelli, for example, wrote that "Among the other harm that it brings you, being unarmed causes you to be despised."
From Operation Choke Point, you can see what is really wrong with regulation of digital currencies, and, indeed, all government regulation. Government regulation at its heart says, "We in the government know better than you what is good for you. We would like to pretend to be able to monitor every business transaction and make sure that only good things are sold to you. Lamentably, we can't afford to actually investigate wrongdoing and prosecute General Motors, say, for putting millions of automobiles on the roads with deadly defects in them. Or, maybe we could do our job in this area, but it might cut into the amount of money we expect to be paid in salaries and pensions for pretending to do our job. Anyway, if you have money and power and influence, hire some lobbyists, set up an office in Washington DC, and sell your souls to us - we already have your bank accounts."
If you don't agree that government regulation is a bad thing, you are probably in the wrong place.
