Every good law has counterpoints. Traffic signals prevent me from driving through the intersection even when there are no other cars there. Assault laws mean you can't punch someone who talks on their phone at the movies. The right to a trial means we can't just execute people we know are guilty.
One of the other examples I've been hearing lately is about Citizen's United. They say overturning it or passing contradictory legislation could hamper Steven Colbert, or limit the ACLU or EFF. Well, yes, it might. But that would be better, overall, than what we have now.
The goal is not to have laws that capture every nuance. Government is a blunt weapon that must operate in a non-discriminatory fashion. Special cases exist that show the friction in every law. The objective is not for every special case to be efficient, but for the law overall to be efficient.
Last mile providers colluding with incumbents to provide preferential access to consumers harms competition in content. Competition is good in the long run, even for the things we like that may appear to be harmed in the short run. There are natural limitations to competition on carriage, we should not extend those competition limitations to making discriminatory deals with content providers.
