But only if you can sell it for more than you paid for it either above or under the table.

You can. Money laundering would use an "NFT sale" as a pretext to transfer large sums of money for some other reason.

Tony in Miami wants to buy $40 million worth of heroin from Carlos in Columbia. When Tony bank transfers the $40 million to Carlos, that's gonna raise eyebrows at the IRS and DEA. Tony needs a pretext. So he "buys" an NFT from Carlos to provide a reason for the bank transfer.

In which case Tony has 40 million worth of cocaine and an nft. Carlos meantime had to pay something for the nft and if the price was outrageous say $10 million dollars then Carlos is only getting a net of 30 million dollars for 40 million dollars worth of cocaine. Which if Tony can then turn around and sell the $10 million nft for $10 million he is getting $40 million worth of cocaine for $30 million dollars. So it only works if the nft was not overbought in the first place but if it was overbought then the numbers don’t work out for money laundering.

Exactly.
