• It's said that Kanade's power draws money from her account for objects she creates, which effectively makes her powers a superpower version of Amazon instant delivery. We know she can't return objects via her power, but why can't she turn around and sell them as slightly used on eBay? For example, the drones she created that cost her 2 million? Why not sell them for 1.5 million online? She'd recoup some of her losses.
