I ask this as a person who takes market forces very seriously: why?
I think it's pretty obvious at this point that these forces are not producing very good outcomes for the population (even if they are on paper efficient in the market-efficiency sense), or at least, that the public doesn't feel like they are. That's causing massive social instability that is threatening nearly the entire developed world. That instability poses a pretty high threat to the approach you're arguing for. Neither protectionist reactionaries, nor leftists, are very well aligned with free-market philosophy, and those ideologies are ascendant nearly everywhere right now. Isn't that a greater threat to free-market economics than relatively mild welfare-state and workers-rights stuff?
(Full disclosure: I am very much pro-labor and pro-regulation, so this is arguing for things I support, but even with your views it seems pretty clear to me that the status quo is dead no matter what you do. Wouldn't you rather have reforms that make the existing system work for the public than a revolution that destroys it entirely?)
