'Black market' is not the same as 'unregulated market': a black market is specifically something that has to operate in the shadows, under constant threat, maintaining their organizations by extra-legal means. So of course its products are sketchy. Liability for defective products and false advertising is all the 'regulation' most markets need, especially now with the explosion of network- and software-aided consumer choice. Such liability, not specific to product type, is what most advocates of deregulation want. Not 'black' markets, just free and open markets – where competition, sticky reputations, and normal legal remedies against dishonesty can work as usual.
