Things covered by copyright aren't property. Hence the need for laws beyond the traditional property ones. Even if you do buy into "Intellectual" Property, the Public Domain disproves all property is ggm.
There exists real property (international waters, federal and state parks, roads) that aren't monopolies. Many other examples exist
I agree that property ownership is not an inherent, natural right. It is a construct of law and all law derives from government. That's not saying anything more than orange is a color.
The rest of your comment is equally baseless (and wrong) opinion.
