Just came up with the idea of using NFTs as software licenses. Of course you cannot stop people from messing around your binary distro, but you can easily verify if someone is legally using the produce, since all licenses are on the blockchain, and they can't fake. You can request the company to sign a unpredictable string to prove that they actually control the wallet which own those license NFTs.

Apparently I'm not the first one thinking about that. But it's the most useful usage about NFT. Blockchain games are optional, but software licenses are not (unless you're a GNU guy)
