I think energy conservation and alternate sources of power are good ideas in their own right, and must be pursued; I just don’t think lower Manhattan will be awash in 2050 unless we cut carbon emissions to a level previously associated with the 15th century, and I’m not going to live in a state of guilty panic over my carbon footprint. If others want to walk around wearing sandy underpants, fretting over what they cannot avoid doing and scolding others for buying produce shipped from Brazil instead of buying local, they’re welcome to it. Everyone needs a purpose in life.

In any case, I suspect that the impulse to bring all these untidy unhelpful examples of flagrant individualism under the steady hand of the Ministry of Rational Allocation has something to do with that fretful busybody insistence that people are simply not living right. If we had Star Trek replicators in every house that would conjure goods and meals out of boundless energy produced by antimatter teased from a three-micron fissure that opened into a universe populated entirely by unicorns who crapped antimatter in such abundance they were happy we used it up, and used their shiny pointy horns to poke more of it through the aperture into our dimension, columnists would bemoan the disconnect between labor and goods, and the soul-corrupting influence of endless ersatz vegetables. You can’t win. Because you shouldn’t.
