Link encryption isn't to protect the contents of the user's
communication. There is no reason for users to trust their
ISP more than a national institution full of people vetted
to the highest level.
What link encryption gets the user is protection from traffic
analysis from parties other than the ISP.
You've seen in the NSA documents how highly they regard this
traffic analysis. I'd fully expect the NSA to collect it by
other means.
