As for a Smith refusing, yes, that could be the case. But there was no consolidation of power and industry as there is in Capitalism. So you could easily find many other Smiths to help you with whatever you needed. Going forward there are many specialized industries many of which are extremely consolidated. So you can't just go to someone else they own a whole spectrum. And that also makes it much easier for China to shut down things, as they could blacklist a whole set of businesses not just one.
