It's remains sad that the name NFT is tainted by scams. In business, we start using NFTs more in various other contexts than "art". NFT technology, without the scam marketplace, has many use cases that we only now start to see benefits from. It's a very good way to digitize assets and use them in business processes.
For you as a user, this example can be interesting: event tickets.
Today, the market is dominated by companies like Ticketmasters and scalpers. Artists have very little control over their ticket price. Here in The Netherlands, some prominent artists started using GET to issue their event tickets on (these are technically NFTs). This gives them the assurance that the audience pays a fair price for the tickets and that scalpers cannot trade it for a higher price. Both the audience and the artist are better of using this technology, than issuing their tickets via Ticketmasters.
I could host my own ticket shop where tickets are only possible to check in if you have a passport and trading is impossible since it is bound to the person who bought it.
And trading can be made possible with the same platform that sells the tickets
Sure you can, but then we basically create the same situation as with Ticketmasters, all tickets will then eventually flow through your company and you can change policies again and we will end up with the same problems. With a blockchain solution (doesn't have to be blockchain for NFT's though) this platform can be decentralized and self managed, the rules are baked into the protocol, it can only be changed with the majority of voting rights. It basically enables the infrastructure for artists to control ticket sales (and reading at the gate) themselves, without having to use an agency. In your scenario, they would still need an agency.
It sounds nice in theory with the decentralization but in this case a governmental website selling tickets would be better
Also since when do NFTs without Blockchain exist?
Why do I think it won't work:
Voting by hardware = voting by the rich/ criminals
If there is money at play someone will buy the majority of the Blockchain by owning more than 50% of the hardware and making it a useless endeavour for everyone else.
