That depends on our definition of property rights and sovereignty. You may "own" the land, but you are not sovereign on that land. The larger society, which claimed and defended the land prior to your ownership claims, has sovereignty over it and thus you while within those borders.

For better or worse, such rebellions are difficult to pull off.
