not trying to be controversial here; but isn't it weird that you can buy semi automatic guns and there's restrictions on radio equipments bc these equipments can mess with the bandwidth used by public services - but similar arguments hold for guns as well.
unfortunately the US decided a century ago that electronics should be regulated federally
So we have decided as a society, it seems. No one ever said policy had to be coherent.
Radio didn't make the date cutoff to be a right in the US.
