Totally agree, but the problem is more that the Government even has the authority to request all of that Data with a blanket warrant for an entire country, in my opinion.
On regulating ISPs I'm willing to compromise because the barrier to entry on the market is too big for freedom alternatives to be in place, but Facebook, Google, Youtube and similar services we use entire voluntarely, and could just as easily switch to an alternative.
The heart of libertarianism is that the Government is not supposed to protect us from ourselves.
