Well, if the market so undervalues that stuff, the logical step would be to go buy other people’s beanie babies for cheap, before people realize how much they are actually worth. And then sell heaps of them for profit, once people come to their senses.

That’s obviously a very stupid idea, that you could pose to her, and let her argue why she doesn’t do that. Maybe it triggers a realization about how value is constructed.
But maybe it’s not worth the risk of her taking up on this very stupid idea.

If all you need is one single mug of hot water, a microwave is the way to go.

There doesn’t need to be any knowledge involved. It happens, because it works. Neither the beetle nor evolution itself “know” anything about quantum physics. The beetle is just a beetle and evolution is not even an entity that has any agency, it’s just a process that’s happening and that leads to remarkable results over time.

This is just one more example for the old discussion how complexity can develop through evolution. The classic example is the eye of vertebrates. Read up on that, if you’re interested in that discussion.
