Everything is coersive. Morals are nonsense or polite conversation. This is old hat.
What matters is that most other sociological theories (assuming we discount primitivism and a war of all against all approach) theories have more nonsense, in the very literal sense of the word, than more market oriented philosophies and outlooks.
Besides all that the word “property”, among every other word I suppose, implies force. Either by stating you can or can not have something is saying something with authority.
This is one of the many reasons why I am not so sure anarchy is a good word at all to use (what the hell is “anti-authoritarian”?):
