Looks like an excellent time for a motivated individual (not me) to repeat the crypto middle man buying behavior that we saw a few years ago. I picture this as a person opening a Moon account and advertising that they can provide a lower price on popular Amazon items by purchasing through them. They use their Amazon account, get the orders, purchase through Moon, have Amazon handle shipping per usual, Amazon knows only that they got a solid sale and the individual creates a temporary market in the middle between Amazon and Moon to provide a service and earn some crypto. My guess is that this would be brilliant for 3 to 6 months before others join to provide the service, or, as you said, it becomes sufficiently normalized that Amazon does it themselves.
I love when these opportunities open. Enjoy watching creative people take advantage of this type of legitimate short term service provision where everyone wins.
