I just remember the day, as a software dev with a solid understanding of Blockchain, my older dev neighbor started explaining how NFTs worked

I thought he was confused or stupid or something.

"Wait, so like you have these super rare images, proof you own it on a Blockchain, and a link to the place they're all publicly hosted?"

Him: "Yep"

"And the only use for these right now is as a profile picture?"

Him: Shrug, "yeah, people use them for discord and stuff"

"But... Couldn't you just download the image and use it anyways?"

Him: "Yeah, it's all publicly hosted"

And it was about then my brain locked up. I did multiple hours of research later, sure I had to be missing something

You can buy medical debt, that has lots negative of value to the indebted.
