And even if you didn't have that little prohibitive transaction cost, and information were at once free and precisely accurate (and even if "accurate" information were available, that doesn't mean it won't be deliberately distorted by its collectors and sorters to influence to just whom resources will go), experience suggests that just because government knows what is the most efficient way to get from A to B, doesn't mean that that is the path it will travel as opposed to one more reasonably calculated to preserve the authority of those in power (
e.g., Solyndra, a company with which to boot Nancy Pelosi's brother or someone is associated). I mean if you can't win the next election, isn't everything else moot?
