“Do you have any support for your argument? Your statement that “no such system exists...or could” seems to have the kind of certainty often associated with bong based science. How do you know what “could” exist? Did you see it in your crystal ball?”
This is the problem with trying to discuss policy with libertarians, you are constantly in the position of “prove it’s impossible”.
This is the reason that “libertarians you will always have with you”.
Almost every other damn fool scheme for organizing society is at least practical enough to have been actually attempted, at least short-term:
Pure communism, brazen kleptocracy, organized theocracy, governance by ad hoc divine revelation, strong monarchy, various sorts of anarchism, “free love”, if humans can dream it up, it has been tried somewhere long enough to demonstrate it’s strengths and weaknesses.
Strong libertarianism however is so utterly impractical that its practitioners have never been able to sustain even a brief experimental attempted at scale to demonstrate its practicality.
It’s so impractical, it’s the only scheme that has never actually been tried!
And absent the attempt, libertarians will smugly ask (in the face of the pretty obvious answer) “prove that it’s impossible!”.
Well, Libertarians threatened to steal an already functioning state with the Free State Project, but they couldn’t even do that. They’ll have to continue parasitizing the societies that already exist, while constantly whining about what’s wrong with them.
