My unpopular opinion is that this guy should be mugged in the streets for running a shitcoin ponzi...but that's just an opinion. In reality, he should be handed to US authorities and serve a long prison term.
Everybody is gangsta until an actual gangster knocks on your door.
Why is it funny? Regardless of how anti-government you are, you're already have a contract with government: they take your money and give you protection. You wish to change this contract, may be even spend time and effort in political activity to get it changed, but it's still there.
The fact that you express your desire to change your contract with somebody does not give them any (moral or legal) right to not follow the contract if it is not yet changed. And especially if, despite your wish to change it, you still follow your side of the contract (pay taxes).
I've already answered that in my comment. You would want to take what's yours according to the contract that you've been forced to sign, even if you are trying to cancel the contract.
I don't know anything about him, but if he is an anti government guy it's very likely that he is indeed in favor of private defense agencies.
