Deregulation often leads to more regulation. By allowing a whole class of actions to happen, you will find exceptions will start popping up and laws will be written to patch market failings.
If you allow X, you will find overtime it will turn into 100 different 'Allow X but' rules.
Example, Cable companies can now charge more for Netflix, then netflix lobbies and gets a new regulation 'Can charge more for traffic Except by accredited content providers'.
On and on exceptions will be lobbied and won and eventually you end up with more regulations and a larger government administering those regulations.
Net neutrality is a far more efficient regulation.
