In the unlikely situation where this happens and I'm alive to experience it, I'll be the most extremist libertarian you've ever seen. "You don't like this? Just create your own community on some planet a few light years from there and do your thing." Communists colonize their own little solar system, anarchists cohabitate in an other, fascists create the Germania consortium.
But that's not the world we live in currently. We're all stuck on the same speck of dust in the middle of an absurdly large ocean of empty space. So yeah, for now unfortunately it means we have to play nice with each other and compromise. Whether you like it or not you're part of a society.
Please keep generic ideological bickering off HN. It's always the same, therefore never interesting in the local sense of the word.
I'm not sure about your claim that valuing liberty for myself and others is about "taking as much as you can for yourself", though...
This is perhaps what separates libertarians from liberals, conservatives, socialists, etc.: we simply do not deny others the liberty we claim for ourselves.
If a monetary system that cannot be debased/controlled by government is available, does that not allow you to elect to create and/or join a community of similar beliefs? Or, would you prefer that I (or someone else) be able to gain control of your government, and then choose to make it (financially) impossible for you to choose your associations and/or behaviors?
Or, perhaps: does your "utopia" require others to fund it, in order for it to work? This is, unfortunately, the case with most people's personal beliefs. They require the non-consensual forced effort of others to succeed...
