IMO micropayments should be so small that people don’t even account for them in expenses. It costs almost nothing for a website to serve a single request, hosting costs almost nothing.

There’s no reason a big host can’t be 100% free, entirely relying on user payments for requests to pay for electricity and new servers (where each request is almost free), a few engineers and security guards to physically install, maintain, and monitor the servers (funded by excess or donations).
