Having worked for financial traders, I got to see up close that some of our most effective markets are very tightly regulated, and for good reason. If a market participant can trust the deals on offer, trades are fast and frequent, and sellers compete on dimensions like price and quality. But if a seller can do well by scamming, that not only harms the people they trade with, but the market itself, in that trust is reduced. That raises costs for all buyers (because they have to do more verification work before each trade), and puts a burden on all sellers (because they have to work harder to prove they're not evil). It also reduces turnover, as increased risk means fewer deals done.

So for me the question is how we get a free flow of accurate information. I think the obvious answer is tight regulation with a willingness to sanction deceptive actors. But for a lot of people, and they seem especially common here, that kind of regulation is anathema, as to them it's the opposite of "free".
