No, I’m not going to sell you on the 42069th cryptocurrency (thank goodness!), I just think that focusing on crypto, and, god forbid, NFTs, completely wastes the potential that blockchains have. Case-in-point: DNS. The centralization of DNS has been a disaster for the internet. The solution: Decentralize DNS with a free register-deregister system. As DNS is now decentralized, hosting fees will decrease dramatically. Laws will also need to be made to prevent DNS-scalping, so as to prevent people from sitting on domains and selling them for high prices. This might be resolved through either domain limiting or traffic tests, where a domain must keep a minimum amount of traffic over time in order to justify it staying registered. Otherwise, it would get deregistered and become freely up for grabs.
As oscardejarjayes has said, the $10 isn’t for computer resources, it’s mostly to pay the customer facing domain registrars and disincentivize squatting domains. Each subdomain (.com, .ca, .uk, etc) is controlled by some entity and for national domains part of the fee is a tax set by and collected for that nation.
In terms of the “compute” required for the DNS – that’s actually your internet service provider. ISPs synchronize and serve up DNS locally in order to give you faster internet (so users pay for DNS indirectly). You might have switched your domain to 8.8.8.8 (Google’s DNS servers) which Google provides for free in order to try to speed up peoples internet access.
