I'm just using tickets as an anchor to something that already exists. My point is that if the credential of owning the NFT were recognized throughout an ecosystem of unrelated organizations, that might merit building it on a permissionless blockchain. Few people are bothering to explore such ideas. I think you're right about it being hard to monetize, but people once thought Facebook was hard to monetize. I guess I'd just say absence of evidence isn't evidence of absence, when it comes to the utility, but a level of outside-the-box thinking is required that no one's motivated to do when you can simply mint NFTs of URLs and sell them for absurd sums of money.
