Cloudflare is trying to push for that, but every time it's mentioned people complain (because they hate Cloudflare for making them wait 2s for a captcha) and nobody proposes an alternative solution. I don't think this is going to happen, unfortunately, and the internet will get silo-ed into oblivion.
My issue with cloudflare is that if I run a VPN it randomly just locks up. Coin toss I can get through if I am routing thorough another country.
People don't hate micropayments because it's Cloudflare promoting them, it's because it truly is a shit idea, for many reasons.
People would equally reject Netflix, if Netflix fooated the idea of replacing the subscription model with pay-per-view micropayments.

Such is the human condition - some problems simply have no satisfactory solutions.
