Nothing about the idea of capitalism dissuades the use of force, if anything it increases it. Theft and violence exist under all economic models, even by those in govt/law enforcement
Personal property laws are a part of a fair/healthy capitalist economy, but they aren't always respected. I think you're confusing capitalism with its fundaments
I also believe that owning assets should NOT interfere with the well being of others. If you own something and it causes other people to die, is it worth owning?
