Why would anyone accept such an NFT?

"Yeah, we can see that you paid someone else for this content, so we'll pay the bandwidth and any licensing fees needed for you to stream/download it from us.".

A business model like that makes no sense.

You pay for the bandwidth, either directly via a subscription fee to the service (Prime, iCloud, etc.) or indirectly by using the service, e.g. Steam lets you import CD-keys for free too, since they value you more as customer than they care about the money lost for downloading games for free.

Also there would be no licensing fees. People paid those when they bought the games. Companies providing those games after an NFT-check would just be a digital storage lockers, not a movie/game/book seller. Content companies don't get to double dip:

The only reason why they get away with that right now is because there is no concept of "digital ownership". Everything in that space operates in a legal gray area. NFTs have the potential to change that and put digital goods an a solid legal ground, as most of the same rules we have for physical goods could be applied to digital ones.
