Seems plausible if you can cover all traces of where your crypto came from, and considering NFTs stay unregulated by legislation/governments.
If NFTs remain a thing after all the hype & fake demand fades then I am sure regulation for NFT purchases will come into effect to combat such practices.
Letting people in law enforcement, and the banks deputized by the AML enforcement agencies, monitor all private financial interactions, in a warrantless dragnet manner, to make a 1% dent in crime [1], is a terrible trade-off.
NFTs aren't money, by definition (they are literally called non-fungible tokens, and money, by definition, is fungible). From a financial perspective, buying/selling them is no different than buying/selling traditional art work, and thankfully there are no AML/surveillance law requirements to report these types of transactions to the government.
So sorry, there will be no warrantless mass-surveillance/KYC of NFT transactions that unmasks the parties to the transactions.
