Content creators could charge by page instead of depending on malware/ad/surveillance revenue. Spam is cut if there's a charge per mail. Scraping abuse goes away, along with a bunch of DDOS garbage.
The impact is a few cents per page or mail, negligible for a human. But if you're consuming a trillion pages per day, you'd reconsider.
Whenever the topic of micropayments for internet content comes up, a bunch of people start talking about payment processors and their floor on prices, and so on. That's not wrong, but it can be designed around and I think it's a scapegoat to avoid confronting the fact that users despise micropayments and we'd rather blame credit card companies for the lack of adoption.
My ideal experience would be I load $20 into the browser somewhere like a wallet in one block (that could be a payment processor step). If I visit a participating page, it decrements my wallet $.01 or whatever.
The downside is the possibility of abuse and tracking by governments, which would have to be handled at the source, not the symptom.
You visit website A,A,A,B,C,D,A,A
At the end of the month, you send your entire 20$ randomly to one of the websites you visited.
This will level out everyone's contribution and reward websites with lots of traffic. It eliminates the need for micropayments.
You can look into international call termination fee fraud in the public telephone network, for more on this.
