the "upside-down wedding cake" no-fly zones around a large percentage of airports in the US. I had to start going WAY out of my way to avoid flying illegally.

Err, you mean Class B airspace? That's hardly a "no-fly zone," certainly not on the same order as the Presidential TFR.

Let's see how much people who defend this, complain when ground vehicle traffic is shut down for a Presidential motorcade, hmm?

It has been about 15-20 years since I have flown, so I am not up on terminology or what changes may have taken place since then. However, at the time, if your plane did not have IFR instruments/clearance, the "upside-down wedding cake" WAS a no-fly zone. A Cessna 140 (which I was flying at the time) is not IFR rated.
