I think you are talking past people who are making the same points you are. I’m not convinced that all LLs are in this naive state you describe. Activism and social justice can and will be forces in any economy, not just a ‘freed market’. Charles Johnson for example extols the values of trespassing private property to protest injustice as happened in the sit-in protest during the Civil Rights Era. I still hold the ‘freed market’ concept as valid, but one that should be discarded if the same harmful institutions end up taking hold, which they probably will.
I’d argue the LL’s draw just as much from Marx as they do Mises.
I like this blog’s concept of ‘polymacroeconomy’. THAT to me is what I’d call a real ‘FREED MARKET’… a market so free it’s not even constrained by its own market forces!
