I think that this is a very important debate, and I hope to write about many of these topics in the future.

Indeed, I think that private property together with free exchange and free enterprise is what makes possible the incredible rise in prosperity that our world has experienced.

Also, when it comes to environmental issues private ownership of natural resources is beneficial, not harmful. See for example the research of the Property and Environment Research Center: https://www.perc.org/research
