I finally saw an explanation that made sense to me.
You're essentially paying for the ownership of a certificate. The certificate says you are the owner of the certificate
Why is that valuable? Well... why is anything valuable? Because people are willing to pay money for it. It's like collectable cards. There's no intrinsic reason a little piece of paper with a picture on it is valuable.
So let's say I paint a picture, and everyone likes it, so everyone sees it online. But then I also make a single certificate associated with the image, and sell that. The buyer doesn't own the image. What they own is like a collectable card.
"Fungible" just means it's not like bitcoin where, for example, my 1 bit coin is worth the same as your 1 bitcoin. With these certificates, mine might be worth more than yours because mine might be associated with a famous paining or something.
Money is only of value because of a commonly shared myth that gives it value. Gold also.
But it's so useful to large economies... isn't that interesting... I wonder how much is cultural and how much is instinct. Did wealthy people make up money and then indoctrinate the youth? Or do humans naturally create artificial value.
I guess a little of both.
I remember as a young kid we had some colored balls. After I decided the green one was my favorite, my brothers wanted to play with it more than the others.
Money exists for almost 3000 years, the reason is to create a medium of exchange.
A society that uses barter as a form of exchange for goods and services would have an extremely slow economy and a lower quality of life (with obvious limitations). Money is needed in a complex society to facilitate the exchange of goods and services, it wasn't created by wealthy people to indoctrinate the masses and it's not necessarily in the human nature to create artificial value, this is just nonsense... it was simply the necessary evolution of the human society when it reached a certain treshold of complexity.
I'm completely uninterested in them, but I don't see much difference between NFTs and collectables in general.
With a collectable you have physical proof of owning it. With NFTs you have a link to a file saying you are the "owner", without any legal covering what it entitles you to. Furthermore: if the party creating that file with info for your NFT stops (e.g. treasurechess/fourthwave stops hosting the nice image you "own"), you are left with a broken link to something that doesn't exist.
With a collectable you would still have the Pokemon Go card when the company behind them stops.
Yeah, it's like those people that buy informercial products with a lifetime warranty. Guess what? After the company soaks up as much money as possible, they can just close it down and your lifetime warranty is meaningless. So you are betting on the product being so good it is significantly profitable for decades...which works for things like Sears Craftsman tools, but not so much for the latest janky plastic slicer and dicer...
There will assuredly be dubious NFT companies that sell NFTs for a fee, gathering millions, who will then disappear with nary a trace.
