If I don't mow my lawn or pick up my garbage (labour) then my homeowners' association or local government can initiate legal proceedings which may end in me not "owning" my home.

Look, I'm actually for taxes generally, whatever you want to think about that, as long as they provide equal value to the people. However, our current system is designed so that any local government can arbitrarily decide that they're incorporated and I'm subject to their laws and taxation. 99% of us work towards putting more into the system than we get back and many do so exponentially.

Land specifically is kind of a special case, in that we can't just make more of it (to a first approximation). There is an ongoing opportunity cost to society to give you exclusive rights over a piece of land, and therefore it is right and proper that you make an ongoing contribution to society to compensate.
