Unfortunately the rightful owner is the Crown, landowners don't even own their land. We all have to live under some rule of law, and for all its warts, British common law is far better than the law of the jungle, where real estate aquisition is done by force and genocide. Britain was guilty of this in the past, for sure, and my ancesters were not very successful at righting this wrong, or getting their land back either. We have to start having everyone live under the same system of law if we ever want to live with any modicum of peace.
