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.

Yes! Sounds fun to me, not sure what you're getting at, it's not supposed to be a business idea! Just a tool I would enjoy having because I sometimes like to buy used things.

This is just "buy low, sell high" but automated. It is no different than what many humans do every single day, just at a much faster clip and with better processing power. Used car dealerships are a great example. If you think its dumb that humans try to find price mismatches in order to make money...well you may hate the idea of capitalism, which is probably a fair take.
