Here's the problem with use-based property systems: When does it degrade? you say 'quickly'. How quickly? Overnight? Over the weekend? What if I go on vacation for a month? Or my hunting cabin in the woods that I use every fall? The market already has fairly clear standards for when a property has been abandoned.
It's not a unique problem. The same issue arises for perpetual-ownership claims. If I build a fence around 10,000 acres of unclaimed land and claim I'm using it as a nature preserve and charging others entrance to any of it, is it mine? There is no absolute standard of how much "labor-mixing" gives one ownership.
Rules for property ownership will always follow social consensus (true no matter how sticky or unsticky they are). If you go on vacation and a squatter moves into your house, it is highly unlikely the community will recognize his claim to your house.
The enforcement of any property rights rules, whether Lockean, Ingalls-Tucker, or Georgist, depends on a local consensus on what constitutes a valid ownership claim. And the enforcement of any such set of rules by a local community will be perceived as legitimate self-defense by the adherents of that property rights regime, and as aggression by adherents of rival philosophies.
