I believe it’s a false analogy too. But why exactly is it false? Is it because taking money from a wallet is obviously immoral and you’re robbing an individual?
If I go to sell an item on eBay (or a pawn shop) and accidentally enter $8 in the price rather than $800, I doubt there is any recourse for me on legal or moral grounds when that item gets bought. Caveat venditor.
Dropping a wallet on the ground is a completely different story where neither party is taking part in a bona fide transaction.
It would be silly to still send an eBay item to the buyer if you accidentally put down $8 instead of $800 as a seller. Or to buy an item if you accidentally put down $800 instead of $8. In both cases I don’t see how you shouldn’t not take part in the transaction.
In the same way people will sell photos of an item for $80 while the product is normally $800. People will think they found an amazing deal but really just be out $80. You could say that was greed talking. It seems more like a scam to me.
