I’ve learned of one interesting pathway from ancap to socialism long ago, as you might have guessed, through Georgism, but more generally - every finite resource that can’t be produced, like territory and laws of nature, shouldn’t be owned and should be considered common property shared by communist means. What can be produced is private property without limitations.

Thus you can own guns, tanks, jets and air carriers, but you shouldn’t be able to fully own territory and patents, because that eventually leads to legally reinforced monopoly.

I think there’s a logical connection from that to what our future looks like and how it will have to be resolved. Unless we want a caste society.
