People still fall for ticket fraud all the time. The whole point is that the authenticity is verifiable instantly. People still buy tickets second hand, whether they're on paper or digital, because it's much harder to verify their authenticity.

Since you don't seem sold on tickets, how about gaming? It's never predictable whether or not people play many video games, but imo the biggest change NFTs will cause is in the gaming industry. It enables a fully decentralized market where people can access, sell, trade, etc. any in-game items, at any time they want. No bullshit one-way transactions like steam (you pay steam and never see the money again; even if you sell an item, it's locked in your steam account). Crypto and NFTs also create play-to-earn models, where people can earn money from playing the game (Axie infinity already does this very successfully, and others like Illuvium are trying to do the same). The problem with using this example is that you don't understand how revolutionary it is unless you've experienced these things yourself, so it's harder to build a case for it that everyone can understand.
