Net neutrality would not be needed if there were no govt subsidies (state, local, or federal) to ISPs that were not also available to every other ISP.
Unfortunately, that's not the case. Comcast, CenturyLink, etc. have all received huge federal subsidies (i. e. corporate welfare).
The Libertarian rule is simple: if you own it, you control it.
Since these ISPs have received federal (tax) subsidies, by the above rule, the public (taxpayers) are considered partial owners, and therefore must have a say in how the ISPs are run--i. e. the ISPs must be accountable to them.
Therefore, neutrality regulation is a must--the FCC must be a proxy for taxpayers who subsidized the ISPs to ensure they don't use exploit their oligopoly for profit only.
