Which is exactly how it should work! This would create competition for the ISPs as there would likely be some who still offer "equal" plans, and they could very quickly spread into an area where the current ISP doesn't offer that plan.
There is also the possibility they could offer special plans such as porn priority for your viewing pleasure, it may just cost more than a normal plan.
The most important factor however is that the government doesn't authorize larger ISPs from having a monopoly in a certain area by preventing competition.
As we otherwise discussed, the culture of suing everyone and everything is a major issue in US business. The situation where a ISP could have an unbreakable monopoly on area and provide only certain kind of services would be really bad.
Defenitly agree wholeheartedly with you on that one. I think thats the root issue with many things right now!
