“Regulation of some sort has to occur.”
Let the free market decide. You are right that different services have different bandwith requirements. The answer, has been to spread costs equally among all users, while offering ‘stepped’ access.
I’ve seen, just in the last 5 years, my access going from 5/hrs a week to having it on demand. All for the same charge.
There is nothing stopping ISPs from doing what they already do, and limit access. Limit the amount that can be transferred and downloaded. Paying per the amount that you use.
Regulation is entirely unnecessary.
By “regulation of some sort” I was referring to the throttling that ISPs do in the course of their business to ensure the maximum service for the maximum amount of users, and related agreements with larger content providers and end users.
I guess that’s the old-school definition of “regulation”, not the new one that infers only government can do it.
