The internet isn’t decentralized the same way: you have single authorities managing routes, DNS, etc. and - critically - unlike blockchains you aren’t trying to have a single global consensus across the entire system. If my ISP updates my IP, nobody else needs to see and process a transaction, there’s no quorum, etc. That trustless design is what makes blockchains so expensive to use.
