The pseudonymous nature of Bitcoin allows savvy users to protect themselves from all types of crime, including criminals with shiny badges. I find it quite useful and I wouldn't initiate force on anyone. (I hesitate to simply say that, "I am not a criminal", because it seems that in today's world pretty much everything is a considered a "crime" if you look hard enough. As an example, I'll invoke Godwin's law and point out that Anne Frank was a criminal according to her government.)
We must distinguish what
is (not) a crime from what
ought (not) to be a crime. The former is decided by laws and courts, and its mostly useless to discuss it except with a lawyer. For the latter, each one is entitled to his opinion, has the right to defend it on forums, TV, bars, etc., and should take it to his lawmakers.
So you seem to be saying that, in your opinion, the only thing that should be a crime is "initiate force on anyone". Well, that is not my opinion. While you may not care for my opinion, you should worry that 99.9% of mankind does not agree, either.
Theft and most kinds of fraud, even if they don't involve any violence, are crimes in almost every country (and I say "almost" just for precaution; actually I don't know of any exception). In fact,
the earliest criminal codes that survive cover theft as well as murder and other crimes. Corruption of public servants (paying or being paid for violations of duty) is generally a crime, even if it is one where the law most often fails.
Taking drugs ought not to be a crime in my opinion; but pushing people into drugs (whether by advertising, by example, by peer pressure, or just by making them too easily available) ought to be a crime; and, likewise, profiting from other people's addictions. Gross negligence ought to be a crime too (like intentionally failing to provide fire exits and safety equipment, failing to do standard safety checks in the design of buildings and machines, failing do standard medical tests or to report contagious diseases, etc.) -- and indeed it is in many jurisdictions.
Bitcoin allows me to enforce my property rights unlike any other asset on the planet. No one can take my coins without my explicit permission, again including those with shiny badges. (Before someone posts the $5 wrench comic, yes I realize that someone can attempt to threaten you until you give permission.)
Again, one must distinguish what
are one's rights from what
one thinks that ought to be one's rights. The former are defined by laws and courts. For the latter, different people will have different opinions. Without a government, those opinions are irrelevant: in a dispute, the side with more guns, more thugs, or better skills will prevail.
In particular, without laws and courts there is no concept of "property". Property is distinct from possession; it is the
right to have possession. If a thief takes your car, he will have possession, but the car is still your property; and the government is supposed to use its power (with force, if needed) to take the car from the thief, and give possession back to you. On the other hand, if you default on payments and the contract says that property of the car returns to the seller, the government is bound to support him in taking the car from you. Ditto if you have possession of money that the government thinks it is their property (i.e., unpaid taxes).
