I'm curious to hear about 'ownership' of public property. If someone plants a herb, is it 'theirs'? What about a tree? Or a pig?
If the simple act of planting a herb makes you 'own' it, what happens if someone plants everywhere (not that unfeasible at 3 energy/action)? Do they now 'own' the entire garden, with no-one allowed to harvest or plant anything?
I'll agree that if someone is standing right next to a particular herb or tree or pig, and they ask "please don't mess with it", it's not too much to ask to honor their request, but having to ask before harvesting a herb that no one is standing next to brings us back to the scenario above of someone planting the entire garden.
Thoughts?
