It's always a dance. Some things are under your exclusive control, or almost entirely so. Some things are effectively outside of your influence entirely. Everything is on a sliding scale between those extremes. Property rights tells us what should be under your exclusive control and what should not be. Possession tells us what is under your exclusive control.

If you start to believe you are a god and can change the universe outside of what you possess, on a whim, into a fully coherent and properly designed system, I can tell you right now, you're gonna violate some property rights and fail to do what you want along the way. Megalomania is a dangerous, foolish, and evil game, as is the mere assumption of reality denying assertions (such as the ones megalomaniacs like to proliferate to be taken up by useful idiots). I don't think this is what you're implying, but I'm saying it anyway just in case you or anyone else reading this starts to go down that path.
