From what I understand, ATC also covers military flights in the US, which gives a pretty good national security reason to have central control over it... at least when a particular party isn't intentionally trying to destroy it along with various other government functions.
I agree - a good example is bridges and bridge tolls. Maybe a lot of people in NYC have crossed the verrazano bridge. "see, most of us have crossed it, I don't see why taxes shouldn't pay for it". The counterexample would be the trucking company, that once taxes pay for it and not tolls, runs convoys of tractor trailers up and down the bridge, rapidly accelerating wear & tear - had they paid on a toll basis they'd be paying their fare share vs someone who crossed in one time 8 years ago.
Well since the Republicans closed shop and went home instead of staying and trying to figure out a working solution, while also having the majority and the presidency, in this case it's easy to determine.
