If buying a virtual good from oneself at any arbitrary price was easy, money laundering would be solved problem for criminals, regardless of NFTs or not, wouldn't you agree?
That's exactly what's happening right now. But before NFTs the most plausible ways were either opening a business accepting crypto (not unlike meatspace money laundering involving cash-accepting businesses) or having lucky strikes on gambling platforms (where you can play against yourself).
For a larger operation going business route is still preferable but on an individual level NFTs are much easier due to ridiculously high margins that have been normalized there.
How do you know this is exactly what's happening right now? Do you work in the sec space or with tax authorities? I'm genuinely asking, as I'm a layperson in regards to these subjects, and, in my ignorance, I don't see the difference between that and, say, Counter Strike skins selling for 15k USD.
To my understanding, all these things leave simple 1-1 paper trails that can be followed later and lead to consequences, but I might certainly be wrong.
I'm trying to separate people who simply don't like cryptocurrencies and NFTs (which might be your case, I don't know) from actually informed thoughts about what's happening.
