There are no central regulatory authorities. You cannot file abuse reports for fraud. You have no way to know if someone is a known fraud or a reputable businessperson. Although word-of-mouth helps to spread the reputation, that’s all there is. There are also no taxes. And until very recently, there was no control on the kind of content that you could sell.
Some communities established, locally, a way to deal with frauds and abuse from either producers or consumers. On a mall, for instance, it’s customary to kick out a fraudulent merchant; but they’ll simply move to the mall next door, defame the previous mall owner, and business goes on as usual. There is no way to file a suit against someone. Consumers have no rights and no way to enforce them, even if they managed to band together to protest (which they do, but are mostly ignored); producers can be ripped off using several techniques, and they have no way to legitimately claim for justice.
If the technology and economy supported the effort, this situation would be a nice test case for the Libertarian dream of private law and justice committees.
