Re: "There's little point in stealing physical objects if they can't be traded without their NFT."
One of the big worries in the illegal art work (apparently) is that fakes are sold to dodgy types because they have little ability to check if its real.
NFT would also prevent stolen art work from even being brought back into the market after its been "found" 10 years later. The buyer can check if the person selling has the original NFT. If not they are either flogging a fake or stole it. This massively devalues stolen / illegal art work.
Imagine the scene: Evil genius has been lording it over the other lesser evil types, inviting them round ot his underground layer to show off his Picasso when BAM the same Picasso come up for auction but auction version they have the NFT* to prove its the original. imagine the sniggering at the annual evil convention. What a dupe...
* OK so Picasso is a bad example due to the recent NFT thing but you get the picture.
