It's hard to argue that as a society we should construct systems that have any goal that isn't optimising (in this example) services. If that aligns with maximising profits for shareholders, then great, if not then the system is not working as it needs to. IMO it's never really about free markets per se, but about competition. If the market is not delivering effective competition, then it should be made to do so. Competition is what aligns shareholder interest with customer interest.
