You are absolutely spot on when it comes to right wing neo-libertarians. But off base when it comes to actual libertarians. And you can use this small point to infuriate any Rothbard acolyte you come across. If you suggest that they aren’t libertarian, and instead just deeply selfish. Having that fact pointed out. Will wound them on a deep personal and emotional level. Because they’ve built their life around having plausible deniability for being assholes.
Actual left libertarians tend prioritize the freedom of everyone. Not just themselves and their property. Many left libertarians refrain from voting out of principle and not just laziness. Voting for something, no matter how much they like it. Could negatively impact someone else’s freedom. The anarchist end get pretty squirrely sometimes still. But on the whole they’re not all that bad. Nothing like their pretend right wing counterpart.
