IMO NFTs suck. They're useless garbage that people are pumping to save high price sales in their history and cheat others. A great example of useless crap is Jack's first tweet.
That said, we can't stop ordinals because we'd have to censor the network, make it more centralized. Ultimately people decide what they want bitcoin to be and if the majority wants to upload their stuff to the network, that's what's going to happen. Trying to stop them would be worse. We don't need another drama like the one Roger Ver was inciting in 2018.
