This may be true, but in many cases, they're also providing a replacement for the regulation. Having a reputation system, holding payments in escrow and such make it harder to get away with fraud or providing low-quality services. It's not absolute, of course, but neither is regulation. No matter what, a few people will do bad things, and a smaller number will get away with it. It seems like relaxing the laws about these things to see if new models provide better solutions to the old problems might be a good idea.
