I can't think of a scenario in which me buying some used stuff on ebay is that serious to be honest, having the AI buy would be a huge risk as well.

> Also if this were a business and you were going to resell it the AI could also create the listing as soon as the item is purchased.

That sounds like an awful grift, but good point, people might use such a system for that.

This all sounds like janky, low margin day trading for physical crap.
