Is there a crypto project with real world use case where end user has no idea it's a crypto project?

I feel like for mass adoption to occur, blockchain tech and crypto needs to run in the background with end user being completely unaware. They simply need to be able to buy the good or service with fiat/ local currency / cash and receive the good or service as per usual without having to deal with the wallets, seed phrases and exchanges etc. Because let's be honest, all of that can be a deterrent and hurdle.

The way I see it working would be as follows:

1. User pays for goods/service

2. Revenue goes into the company treasury

3. A percentage (e.g 20%) of the treasury is used to buy the token off exchanges

4. Token can either be burnt or distributed to certain community members as payment for their efforts in furthering the project

5. Remainder of revenue used for normal business related items

6. Rinse repeat

All this Cex/dex/defi/nft/gaming and every other crypto related stuff seems to be stuff being invented for people in the crypto space rather than regular Joe's, mums and dads.

Keen to deep dive into any suggestions because I'm more of an investor into businesses than someone who really understands the intricacies of crypto.
