If the concern in the distortion is that people don't pay taxes, my comment is valid. If the concern is for the people themselves, I'm not sure what the problem is with low population density. It doesn't even need some government program to correct if we decide it is bad for society. People already have social and economic incentives to live near eachother. Also, I'm surprised you would suggest that law makers give a shit about the distortion taxes cause, and hope to minimize it. A politician's actions can pretty much always be directly tied to motovations to increasing influence and getting elected. Altruistic politicians that actually care about society don't exist.
