You forgot to mention - bluetooth also uses 2.4GHz
Most cordless phones use 2.4GHz and they also use spread spectrum - constantly hopping channels to avoid spying on your phone.
Most AP use fixed channel, some use "turbo boost" which means they use all channels for increased traffic speed.
I know my cordless phone (2.4GHz) kills my AP - causes it to reboot when the phone rings - a bug in the AP.
So, many devices use the channels for short bursts of traffic - if two do it at the same time, both packets get errored.
None of the above devices care if any channel is already in use - they only try not to use it at the same time when someone else is transmitting.
I see no harm in constantly hopping channels - it's already done by many devices, and it utilizes the available bands better.
