The argument against cars also holds that people should live in places where cars aren’t necessary to avoid hermitude in the first place. You don’t need cars to socialize if you can walk to where people are, you don’t need cars for supplies if you can walk to where stuff is.
Long distance travel can have non-car solutions but also it shouldn’t be the default distance to be away from society.
While I don’t disagree with the sentiment, exo means outside.
