I think the ISP bit is an unnecessary and distracting part, but the general idea is good, I think, for everyone to pay a fixed amount to get access to all content, and then the creators' slice of the payments is determined by what people are actually actually looking at. That way, no one has to think about whether a given article is worth it, nor sign up for every service individually.

Jaron Lanier promoted that same basic scheme in You Are Not a Machine (2010).

It would also eliminate much of the incentive to bypassing paywalls.
