I'll start by saying it doesn't matter whether you get it. The GP made a claim that there is no use for the technology which is not a scam. But people, today, are using filecoin to store files and are not being scammed. It doesn't matter whether you personally would want to use Filecoin; the point I'm trying to make is that claims of the form "the entire space is a giant scam" are simply false.

But I'll also try to answer your new question: You're right that it's just an auction to provide a service, but crypto enables the auction!

S3 can charge such high margins because they're a trusted brand, the chance they'll lose my data is much lower than the chance I'll lose my own data, but this makes it hard for anyone else to enter the market without spending a lot of time proving themselves. Filecoin includes fancy cryptography and incentive schemes which, if you trust them, allow you to trust any storage provider using Filecoin.

Crypto payments means that anybody, anywhere in the world, can participate in the auction without spending any time negotiating contracts or setting payment rails. They can turn their computer on and start storing files.

This turns file storage into a commodity service and allows you to store your files for commodity prices, that's an incredible win!
