More concretely, I think the market mechanism has its place, but I think states need a diversity of economic power & political representation, a reasonable level of wealth/income equality (far more than the current USA at any rate), enough enforced transparency to catch fraud and corruption, and widespread civic engagement at every level from neighborhoods on up, so that political discourse stays informed and productive and the interests of the few aren’t able to trample on the basic rights and needs of the many.
State supported markets and money and property rights are tools, not ends in themselves. Their purpose is to efficiently allocate resources and encourage innovations, so that the economy continues to produce the infrastructure and goods we need to support human flourishing, not to build feudal empires for wannabe aristocrats. At the point they stop serving their proper purpose, they should be guided back by additional institutional structure.
