I've never understood that argument either, on any issue. Most states are smaller than countries, and if on the federal level there aren't any economies of scale or mind-share synergy, then something else is very wrong. If a small country can do it, a large country should be able to do it much better, either per state if there's gain in small scale solutions, or on a federal level where you only have to solve the problem once for 30 times the population size.
