I think my disillusionment with the "Libertarian" movement can be broken into two halves, both of which boil down to semantics when you think about it.
The first is economics, and the begrudging admission that it is, at this point, impossible to separate the "bad" of capitalism (cronyism, corporatism, etc.) from the "good" (free enterprise, individual ownership etc.) without it fundamentally becoming something else in a modern context.
This is why I call myself a "free market Anarchist" and not an AnCap; it's because that while I do think free markets are the way to go, I can't live in the delusion that the monster "capitalism" has been perverted into by oligarchs and billionaires can be fixed by restoring "real capitalism," any more, I think those days Ron Paul pined for in those books I read in high school are probobly gone forever now.
The second is the simple fact that they will *never* leave you alone. Galt's Gulch is a fantasy and it will never exist. You can't fuck off to a cabin in the mountains, because the state will eventually come and take your cabin no matter how many guns or bars of gold you have squirreled away.
If the state is allowed to perpetuate it will inevitably become a tyrannical dictatorship (we're already there in all but name), this is what "Minarchists" don't seem to get, the state is a germ, and if you don't kill it then all you're doing is treating symptoms. And if we're going to eliminate the state, then we need to completely retool society to create something compatible with anarchy, we can't do that by digging our heels in and buying crypto.
Whatever productive form that takes, whether it's AnComs making functional communes apart from the state, or Agorists replacing state functions with counter-economics, I'm with it. Your flag can be any color as long as it's black.
