It's important to remember, all markets are regulated. A market that is not regulated will be regulated by the biggest player to the biggest player's benefit by any measure it can, up to and including criminal activity if it can get away with it.
Government regulation of the market is not, or at least should not be, about increasing the government's power over the people. It is, or at least should be, about protecting the general public from the abuses of other players on the market. There is, in fact, nothing at all wrong about regulating the market to protect organizations on the market from abuses performed by the public on them, but that's an exceptional circumstance. More common is larger groups (including companies) abusing smaller groups (including companies) and individuals for the larger groups' own gain, which is often but needs not be monetary.
