It's also the sort of thing that has to have been thought up by someone with nothing better to do, given how ridiculous the premise is. You would have to assume the adversary is someone with the technology to build rockets, literally rocket science, but not the technology to build their own GPS receiver, which is simple 1970s radio technology?

Worse than that, it's 20th century radio technology in the 21st century when everyone has access to FPGAs and SDR.

The number of innocent people with model rockets or similar being negatively impacted by that rule is infinitely larger than the number of adversaries because the number of adversaries being impaired by it is zero.
