I think it's fine, if you're going that fast, you can't be anonymous. Airplanes aren't, missiles sure as shit aren't, the whole atmosphere is under surveillance for anything larger than a baseball.
I fly a light sport plane (Canadian Ultralight which is not the same as a US ultralight) in airspace controlled by the military over an airbase. It is frankly astounding how often they lose me on radar coverage while in their airspace. I have a Mode C transponder blasting my data out to them as well.
The capabilities that the military/government pretend to have are VERY different than the capabilities they actually have.
