Is there any state activity, socialist or otherwise, that does not represent theft of moral agency?

If there is to be free education, free healthcare, or free anything else, then the providers need to work for free. I'll wager they won't.

There are other ways to structure economic, financial, and monetary systems than the, all too familiar, socialist nightmare, or the unicorn free market which has never been seen.

As long as the state continues to exist, I expect that a free market will not.
