Where did YC state it's the "biggest problem in the world"? Where did YC use the term "moonshot"? This is just one of about 200 companies YC has funded in this batch alone. Some of the other ones are working on humanitarian problems, and over the years YC has funded many non-profits and companies working on humanitarian problems, as well as putting huge funding towards research into basic income and medical challenges. There's no opportunity cost issue here: YC seeks to fund every project - commercial or humanitarian - that seems to have some chance of succeeding or leading to some kind of valuable breakthrough. You should point to a case where they've failed to do that if you know of one - I'm sure YC would like to know about it.
