Yes, if I was the American government. However, I am not the American government. I am okay with killing some people, like violent recidivist criminals.

I am defending the use of violence to enforce laws. And I am also condoning taxation btw, because libertarianism and anarchism is utopian drivel. It's a seriously deficient ideology.

In a more bitcoinized world, it will be easier to choose which country gets to tax you, and states will have to compete more for your bitcoin, but taxes will always exist as long as there are states. Let's leave it at that.
