> I think that's why I'm surprised I don't hear that more. The size of someone's back yard or height of their fence (to a reasonable extent) seems like it wouldn't harm someone else, but they're strongly regulated in much of CA's single-family zoning.

I'm not sure what you mean, but to clarify: the libertarian position is that if the fence harms no one, then there is no one, not even governments, to have anything to do with said fence besides the fence's owner, as that is the owner's right.
