"For starters, a huge number of assumptions are being made, such as about the possibility that approved flying sites will decrease, etc" This is not true. The NPRM specifically states that over time the number of approved sites (FRIA's) is designed to decrease. They can only be requested for 12 months after the regulation goes into effect and you are not allowed to request more and the FAA can remove them at any time.
" It just means they need a transponder on them" Not exactly true either. You must purchase a new UAS with remote ID built in according to the NPRM. There is no transponder you can buy. It has to be preinstalled in your aircraft and tamper resistant. That means no more home built drones or model aircraft built from parts of your choosing.
"Finally, out of all 4 drone owners I know, every single one has knowingly broken rules." Out of the 100 people who I know drive automobiles, every single one of them has broken the rules.
"It doesn't affect tiny drones less than 0.5lbs." Not entirely true either. Anyone flying under part 107 ( that includes people reviewing 20g tiny whoops in their back yard for their YouTube channel ) must register all drones no matter how small. That means if you fly under part 107 even sub 250g drones must comply with the remote ID proposal.
And finally, the privacy risks are real. Myself any many other model aircraft operators have been threatened with physical harm while flying completely legally. Broadcasting the location of the operator to anyone around the world is a serious invasion of privacy and will result in someone getting killed or seriously injured. Which, by the way, has never happened from the recreational use of multi-rotor drones ever.
So please, if you are going to speak out in favor of this regulation, at least read and understand all 300+ pages of it.
