Plenty of people claim that it does. That is the entire ideological premise you invoke with the free market fetishism (laissez faire, Chicagoan school, Austrian economics) the “free market” means free to exploit consumers, not free to choose. Consumers do not have enough capital to afford any meaningful check against corporate snake oil. This over simplistic narrative youre spinning doesn’t match up with the track record.
Also, you don’t have to be an authoritarian communist to know that the free market is a crock of shit. Anybody with the ability to look at the past few hundred years would know Friedman hayek rothbard and most all libertarians are absolutely full of shit or just plain misguided
