I would much rather have a private company that I have recourse to (by using my feet) than the government telling private companies what can and cannot permit on THEIR lines (Yes, they ran THEIR OWN Fiber to my utility pole).
I hated Comcast so I went with Fios. When I start to hate Fios I will go with satellite. When I hate them all I will get a wireless connection, etc... Let the market work!
I have no such recourse with the government bureaucracy.
A lot of people have no recourse. The ISPs have worked out monopoly agreements in many areas. In addition, only a few ISPs have most of the US broadband market (even if you are getting from someone else, it's likely their upstream provider is one of these few). Should they agree to do these things, few people would be left with recourse.
In a free market, the ISPs would be scared of losing customers by violating net neutrality, but right now they don't have to be scared, so they can do pretty much whatever they want. Right now the only people being hit are those using P2P, and most of those are probably illegal, so the ISPs feel comfortable blocking or restricting P2P traffic (they don't like it when customers actually use the bandwidth they contracted and paid for). But the ISPs have stated their desire to do more.

As initially stated by the FCC, and before the Democrats got their hands on the issue, there was no need for more buraucracy. Under the rules, companies had to disclose their practices to customers (this is more a consumer protection move, not actual net neutrality), and not discriminate against the bits flowing across their networks on the basis of origin, content or application. The FCC would handle complaints of net interference, such as maybe Sprint slowing VOIP connections in order to push their own VOIP solution that just happens to be faster because it isn't throttled (thus trying to kill competitors like Vonage and Skype through ownership of the last mile). Reasonable QoS was allowed.
BTW, the first "net neutrality" law was already passed to manage an encoded, bit-based network across this country. It was passed in the 1800s, and said the telegraph couldn't give priority to some civilian messages over others, but had to send them first come, first serve.
