You wont be able to strip away peoples right to own private capital without force? Even if we pretend that the government was able to somehow democratize majority of the economies captial there would still be the issue that we see in all socialist/communist countries where government workers are a tier above everyone else and abuse that power both directly and indirectly.

If you cant own anything yourself then you are forced to rely on the government for everything and hope that they are benevolent. If America magically became socialist today, trump would be the leader, do you trust him with absolute control over the entire nation?
