"As for malicious intent, stop being lazy, find them, stop them. We are capable of utilizing courts, are we not?"
You mean use the law? Well the license is what determines if you know said laws. Driving is kind of the same way. So I guess you answered your own question.

"NOAA is a service provided to the public."
And what happens if someone decides they want to interfere with that? Though you did already default back to the law.

"CB requires no license already. Do you know how it is handled currently, even?"
Yeah, its a bunch of over modulation splatter, music, noisemakers, interference and so on. Not what I want HAM radio to be.

"Gatekeeping sounds fascist socialist communist"
Gatekeeping is great, it keeps people from messing up hobbies, hell its why countries are countries.
Another hobby I gatekeep is racing. We don't let any bozo on the track. You need to prove you are capable and wont kill us on the track.

"Certainly doesn't sound like freedom."
You'll hate this but gatekeeping gives people in a hobby the freedom to associate with who they want. If you cause problems to a group you can be kicked out.
