To answer your question; because any federal law passed by congress in an effort to improve consumer choice in the ISP market would require the signature of the president without a supermajority. However, my call for answers to these questions applies equally to candidates for congressional, state and local offices too.

Unless you feel the current regulatory structure has no responsibility for getting us in this situation, how are they not pertinent?

You use phrases like "improve consumer choice" and "regulatory structure" as if it was possible for your interests to be aligned with those of the regulators and politicians. Nevermind those being regulated are donating many, many times more to politicians than your interest group is, to either not be regulated or regulate their competitors out of the market.

It's called democracy. I'm sure there's an excellent civics course online somewhere.
