I’m super late to this, but I don’t think it’s correct to call Chase Oliver a left libertarian. Right vs left in the context of libertarianism is capitalist property rights vs socialist or mutualist property rights. Oliver is clearly on the capitalist side. He’s a bit culturally lefty as a former Democrat, gay man comfortable with Pride festivals, and an antiwar activist, but culturally lefty isn’t exactly the same thing.
That’s kind of like saying Mitt Romney and Liz Cheney are left conservatives by the standards of the Republican Party especially after the takeover of Donald Trump in 2016. It’s kind of a ridiculous definition.
