I'm curious to understand how you've decided that your desire to take someone else's property makes it a trivial truth that only violence prevents you from having the natural right to take it.
I never suggested such a thing. Natural rights don't exist. That's just something some people make up. So what prevents me from taking someone else's stuff, if I really wanted it?
The same thing that prevents you from killing people that you really don't like, I guess? I assume you don't do it because you are at least a half-decent human being, and not because of the threat of violence. Same with taking property.
