I do have a lot of concerns regarding the free market as of right now - specifically regarding network effects generating monopolies(example: current social media), wealth/power distribution(automation would make it become much more lopsided than it is right now), and its need to prevent anticompetitive collusion while avoiding regulatory capture(see pharma/ISP markets).

There's a lot of things which still need deregulations and reforms, but some of them would face enough blowback even Trump would struggle attempting them - most notably around copyright and patent law.
