Just like crypto or Hertz stock, people will buy NFTs because they expect tomorrow or in 10 years there'll be a bigger fool that will be willing to pay them even more money to own the thing. (This is the "greater fool theory").

At least classic cars or limited edition supercars actually have proper scarcity, and they are things that can actually be enjoyed and shown to people for bragging rights (i.e. to gain social value) or to attract a mate.

In my view NFTs is just yet another digital ponzi scheme, kudos to whoever came up with it, even Jack Dorsey saw the $$$ and got attracted to it.
