One problem - there is only so much bandwidth available in a certain portion of radio spectrum. If everyone started doing what you are doing then “most people” would be seeing pretty bad performance. Wired is always better; especially in higher density environments. If you are in a rural or low density area then this is obviously less of an issue - but everyone moving to wireless would be an utter disaster where most people live.
