In the long term, bring drugs to people without thorough testing and regulations. It's one thing for e.g. stage 4 cancer. It's another to let a Vioxx get through.
Strict regulations around the development and testing of drugs exist because no human is capable of evaluating efficacy for themselves, absent stringently controlled testing processes.
We laugh about "snake oil salesmen", but given the amount of money in nutriceuticals, GNC, and the like... I'd say the only damn holding back the torrent on the unsuspecting is the FDA.
