Why do you want protection from me? I have not given a slightest hint I want to harm anyone in any way and I don't like violence. Why would I fear rules? I fear people who want to randomly enforce those rules, justifying by them anything they want to justify, while themselves avoiding the rules they created for us. Besides, it is exactly high ranking government jobs that attract sociopaths, because it becomes really easy to do anything with very little accountability.

Interesting. So why did they check mine upon exit? I haven't indicated in any way I'm not a US citizen.

In theory. In practice, no airline would let you board without a passport when going on an international flight.

And then? Does government ever say "oh, nevermind"? After a couple of notices your bank account will be frozen, or your passport "revoked" etc.

That you might pay your taxes voluntarily is charming, but do you really think that if all enforcement behind tax collection is lost that most of the population will pay their taxes?

Society != government.
