Some people like living in communities that look nice. It seems fair that you can opt-in to those rules by buying in an HOA, and if you do want to park on your lawn, buy elsewhere.

(And I am not a fan of HOAs personally, so I do in fact live elsewhere, but my neighbors house is also an eyesore)

Yes indeed! One of the reasons I'm personally happy to live in an HOA after having lived in an area where lawn junkyards were common.
