The entire point of NFT's is money laundering, which is why they are worth so much. People are not buying the artwork, that is just a legal loophole to escape duies and taxes. They are buying the crypto has connected to that artwork which is unique and uncrackable. Thus they can buy and sell that to transfer value across borders without having to move cash, and thus incur duties. They can even play games with deductibles like "donating" the NFT to a charity they control, geting the tax write off, then "gifting" it to a shell corporation they control from there to sell it again.
