That's partly because it's nearly impossible to build a telecommunications network in the private sector, due to the fact that you don't have eminent domain power, can't dig up roads, etc. And if we're going to have the government assisting private businesses, granting them local monopolies, etc., then sure, they should be regulated.

I never said the US broadband industry isn't regulated, I was just correcting an economic misconception of his. It is entirely true that if the broadband industry were left completely unregulated, there would be a few dominant players in the industry, and their dominance would be a result of the high barriers to entry, and not because of their inherent superiority.
