It's basically the same sort of estimation that happens when watching Shark Tank and wondering, "Well, that's a nifty product. What are the margins?"

Essentially, you're saying it's okay that people can spout basic science, but still can't apply it in their actual lives in a market economy. Shouldn't that be the lower bar?
