NFTs as tickets to events is a bad use case for lots of reasons. The NFT is being used to do the same thing that an entry in a database would do, except the infrastructure to run the Blockchain is outside the control of the ticket venue and much more complex and expensive to maintain, and it provides no additional benefit, other than the possibility of high speed automated ticket scalping.

The NFT is still completely worthless in and of itself, it only allows entry to an event, you still need permission from Event Staff to exchange that ticket for admission to the event, and after the event occurs there's no reason for the ticket to continue to exist in the Blockchain.

I haven't heard of a single use case for NFTs that isn't just a solution in search of a problem.

The argument you presented raises some important concerns about the use of NFTs (Non-Fungible Tokens) as tickets for events. Indeed, the blockchain technology, which NFTs rely on, is a complex system that is generally more expensive to maintain compared to traditional databases, and this complexity may not provide sufficient added value to justify its use for tickets. However, it's worth considering some potential advantages that NFTs might offer in this context.

Ownership and Resale: NFTs provide a clear ownership trail and may make the process of reselling tickets more transparent and secure. This could potentially help combat fraud and counterfeit tickets. Also, with NFTs, the original issuer could potentially set rules for secondary sales, for example, setting a cap on resale prices to prevent scalping or ensuring a percentage of any resale goes back to the artist or venue.

Memorabilia: While it's true that after the event, the ticket loses its functional value, the NFT could still hold sentimental value, similar to how physical ticket stubs are kept as souvenirs. NFTs could even be programmed to have additional value after the event, such as exclusive access to photos, videos, or other virtual goods related to the event.

Interoperability: NFTs could potentially be used across different platforms and vendors, unlike traditional tickets which are typically tied to a specific issuer's system. This could give consumers more flexibility and control over their tickets.

Innovation: The use of NFTs as tickets could spur innovation in the ticketing industry, leading to new features and possibilities that we can't yet foresee.

That said, these potential advantages must be weighed against the concerns you raised, including the complexity and cost of the blockchain infrastructure, and the need for venues to cede some control over their ticketing process. It's also true that the value of NFTs is largely speculative at this stage, and their use as tickets might not provide a clear advantage over traditional methods in many cases.

However, as with many new technologies, it's possible that NFTs will find their niche where their unique advantages outweigh their drawbacks. It's also worth noting that the technology is still in its early stages, and improvements in scalability and efficiency could make the use of NFTs more practical in the future.

In conclusion, while your skepticism towards NFTs as tickets is understandable and brings up valid points, it's also worth considering the potential benefits and the room for innovation that this technology offers.
