Imo the reason this doesn't exist is the Visa/Mastercard duopoly, which enforces a per-transaction fee of $0.30 or so, which prevents micropayments from taking off. Solana (or specific other cryptocurrencies with tiny transaction fees) would actually work for this but well then you're using cryptocurrency, with all that implies. But a JavaScript library that charges $0.001 cent for each "read more" link clicked would be such a system. But how do you get blogs to add this library? Still, it is an actual use of cryptocurrency. Just don't say mention Web3 and we'll be good.
