Sprawl is messy, chaotic, and sometimes annoying. In short, it is everything one expects from a free and democratic society. Leave the neat and clean societies for totalitarian regimes. Sprawl creates problems, just like every other social trend; but to damn it for its problems is akin to outlawing the sun for causing skin cancer.
Robert Bruegmann reminds us that much of the anti-sprawl crusade is a result of a rising level of prosperity, and the complexity of millions of individual decisions made on a daily basis by millions of citizens. Better to have to deal with long commutes and strained infrastructure than malaria, cholera, or declining life expectancy.
In terms of problems, I'd take sprawl any day.
