To be completely fair about the stupid liquid rule, it was prompted by fears about someone making TATP on the flight. The precursors are not particularly dangerous on their own.
Given that control of liquids was a reactionary measure to an event that didn't actually harm innocent people or endanger an airplane (and was incredibly unlikely to begin with), it's debatable if it warranted any attention at all.
But, between you and a buddy or two, that's still a lot of precursor. It's not like they've actually solved any problems; they've just made the 3oz toiletries industry boom.
