We also have the option of taxing ISPs and then handing that tax to creators (according to legit page views). That way that the ISPs collect the fee for creators seamlessly. A bit like gas taxes going for highway construction in the fifties. Wouldn't it be great if newspapers paying reporters made sense again?
There's no reasonable way to apportion payment for content by metrics that ISPs can see that wouldn't be horribly gamed and bad for users.
Pay per page view is obviously out because what is a page view? Pay per byte is inviting pages to get even bigger, no thanks. Pay per connection or DNS lookups or time of connections is all easy to game in JavaScript.
Save the absence of better alternatives, perhaps. And you have to examine all the alternatives to the present disaster for content-creators in order to pick the best one.
