This feels very pie in the sky and dreamlike. Of course some corp will figure out something to do within this space and make closed products that push out free and open uses. At least that's my pessimistic view opposed to your optimism.
If you pop open a spectrum analyzer in most places, you'll see a ghost town in the Cathedral and a hopping lively Bazaar in 2.4/5GHz. On net, it is good that more resources are going to the Bazaar.
6ghz is pretty fragile -- i can't imagine one product "pushing out" another when a wall will block the signal. Just don't have the closed products in your home, and the open ones should work just fine...
