spend 2 minutes on an NFT marketplace? there are many trades between addresses that have registered aliases via ENS, which is the best way to determine if something is not a wash trade. Noteworthy is that you are starting from the opinion that things are wash trades, while the NFT users are not, and given the amount of energy necessary to support this opinion from someone not even participating it makes me wonder if any observation is possible to contradict your stance.

would you like a specific trade to debate? does it have to be $600k for this standard? I see some decentraland plots recently traded for $20,000.

thinking further about it, its easier if you owned an NFT other people were interested in, because then the bids - if they arise - would be from other people and you'll be one less person that would hold the likely wash trade idea. many NFTs are free to acquire during their initial creation.
