If dem bulbs become mandatory (and there's still a chance to avoid that with legislation), they will spawn a black market just like we've already seen in toilets. Since the environuts got regulations to outlaw toilets that actually flush, plumbing supply houses in Canada have made a fortune selling the models that work, for smuggling back into the U.S.
There are countless really, really irritating and stupid government intrusions into our lives, like dem bulbs, non-flushing toilets, catalytic converters, seatbelt interlocks, plastic bag prohibitions, absurd non-smoking rules, hugely excessive handicapped parking, and everyone has their own list. Virtually none of the really stupid laws exist in legislation. None of them were ever subject to a vote by us or our representatives. They are all regulations written autonomously by zealots, to carry out what the zealots interpret to be the intent of legislation. But every word those zealots and environuts write becomes a law without being approved by the electorate or our representatives. Changing out low-level regulators and bureaucrats is as important as electing congressmen and senators, but it never happens, partly due to civil service rules, written by the same zealots.
