Everyone should be able to wash trade NFTs, even poor people. Which is why there should be a service.

If you die how much will your NFTs be worth? Will they go up?

Cryptopunks were most definitely wash traded to go from free (zero dollars) to worth millions or hundreds of thousands.

If OpenSea or other NFT marketplaces are decentralized then they can't prevent wash trading. 

OpenSea has to be careful in what it says is true (meaning their UX) saying what are legit transactions.

After all all OpenSea does if they are actually decentralized is put a friendly wrapper that says which transactions happened by you telling them your wallet address.

The only person you have to worry about getting you in trouble for wash trading is a angry customer- just make them happy if they sue you for buying your NFT and not being able to sell to a new sucker. However if they are able to sell to another sucker, you are off the hook for fraud because there is someone in between the two of you, unless they go back to you for the original fraud. 

Follow up- didn't discuss- Find someone who died, but before they died they created some NFTs.... scarcity is already set. Narrative of death in play. There could be an entire platform on death NFTs. I kind of like that concept.

Follow up question- uniswap price dynamics--- bored ape project called uniswap pricing mechanism a ponzi-- makes wonder why did they launch like this-- selling all for same price - 200 instead of an auction
