It is not your property. If it were your property you could build whatever you wanted so long as you don't bring harm to others. The word you're looking for is not property owner but "tenant."
You're confusing property with what they told you it was.
Property is an illusion. Still confused?
Property is a concept, different people can have different conceptions. I'll take your word for it that your conception is a delusion. You can't speak for everyone else though.
