I say why not, don't we already forfeit large sections of our waterways to the loud and obnoxious. Our society doesn't value peace and tranquility, we look at our waterscapes as playgrounds for idiots and we even admire those who turn them into amusement parks.
As for regulations... we all know that's a bad word.
When I'm an old man I think I'll give up all public water and spend my time trespassing on tiny creeks. I'd just as soon take my chances with gun toting, paranoid red necks. If they want to kill an old man with a fly rod I'll accept that fate.
