A Ferrari 250 GTO will keep up with Bitcoin because only a few exist and with time they will go even more scarce...

Countless items have that attribute (scarcity) - including NFTs.
Certainly, Ferrari has proof of work embedded in its brand which is why it’s better than an NFT and more likely to stay valuable.
However, I don’t see anyone bidding up the highest end horse drawn carriage from 1880.
