Why cant i just walk into someone else cabin and say its mine - i find the concept of ownership ridiculous. So what you built it? You left it half an hour ago

Why cant i just walk into someone else cabin and say its mine - i find the concept of ownership ridiculous. So what you built it? You left it half an hour ago to collect wood- i assume you want to build another one and are sick of this one. What do you mean, permits and claims? Calling the police? This is all very regressive talk i hear here. Turns out there are two sorts of Freedom - the good one (mine) Freedom and the bad one (others/your) Freedom. I will rage and fight for the good freedom, while demanding for someone else having his good freedom and parts of mine good freedom to limit your good freedom.
