Ghost of a flea

I'm hardly the first person to say this, but that's my main gripe with many libertarians: their arguments have the internal purity of rock crystal but are useless for a country of 300 million strong-minded people who all have to live with each other.

I'll never forget a meeting of libertarians in Berkeley which turned into hours of arguments over whether handguns should be allowed to be sold in vending machines to elementary school children. (Yeah, sure, there's a "principle" involved, but it's about as practical as debating how many angels can fit on the head of a pin.)
