Nobody trusts a single SQL database or any single developer or company. The advantage is that you have a trust less, decentralised database no one can alter and has thousands of people hosting it.

This is a common fallacy I’ve seen among developers - the idea that because the technical solution is inferior it’s social value must be inferior. Blockchain is not a technical solution, it’s a social solution. At least as far as NFTs it has solved an insoluble problem, which was no one trusted anyone in particular with a ledger about digital art ownership - but they do trust everyone/a a large group that’s incentivised to keep hosting it, and has problem to be tampering resistant.
