In Michigan, teams advance to the state playoffs based on their performance at regionals. They do make an allowance for exceptional individuals on a weak team. If the #1 singles player makes it to their regional final they are automatically included in the state playoffs (without their team).
I like like that Mitch is trying to find ways to create more interest in tennis. I tend to agree that this needs to happen well before high-school and that the proposed changes may not be practical. Still, it never hurts to talk about it.
