there is no control of who uses the airwaves the radio with the most power wins that frequency.with millions trying to get on the air HAM would be a lost bet for most users.
also it would be a source of misinformation for folks like me who just have a receiver.you could never trust any info and how would you know if a official station was real.
It's a valid question to pose, certainly, but I wonder if that's really the case. Maybe on the 2m repeater bands it's more of a wild west situation. But it seems to me that HAMs have been through many a dark crisis and have, as a community, maintained a broad base of respect. This is earned, not given.
I suspect HAMs regulate themselves individually and as a culture the same way we regulate ourselves individually/culturally in this forum. We do not have the right to do as we please; we have the privilege of participating. We give each other a kick under the table if we're pushing the boundary. And if we overstep, there is that giant Monty Python foot, poised to thin the herd.
