Why does the government need to get involved?
have the national organization for RC planes do something about it

The national org has a whole membership tier just for those ParkFliers,
they should take the lead in kicking the PFs off to some subset of the RC freqs and mandate the rest of the freqs for non-PF.

What is stopping the national model airplane org from making it happen in-house,
as an example of how easy it is to do and how well it works.

We just divide up the 72mhz channels,
150k standard RC guys get 55 freqs,
2mil+ PF guys get to fight over 5 freqs

hmmm, even government can see that aint right... wouldnt the government make it
150k glow & gas guys get 5 freqs to share
2mil+ Park guys get 55 freqs to share
