Seems like only mainstream production companies would bother adhering to the regulations, meaning all of those other examples would remain available to everyone. That'd increase the ratio of freely available "bad" porn to "good" porn. Perhaps there are good intentions behind this law --although I suspect it comes from pressure by hate groups -- however this is not the way. Seems like involving parents and educating kids is the best option.
