A better idea would be a non-profit federated subscription similar to music services. You just use it, you don’t have to think about how much you pay for each page you read, and the federation keeps your identity private. You could even upvote or downvote a page if you wanted more of your percentage to go to someone or none of it. You could decide how much you could afford to pay so it could be affordable and free to the poor. You could vote even if you didn’t contribute and your vote would be considered equal.
But, the odds of that becoming a thing are incredibly low. It would require some sort of identity, which could be misused. And the web is meant to be like the outdoors- you go outside and move around in it mostly freely. It’s not a zoo where you pay admission.
