People need lots of things that they won't buy because they don't care. People need to eat healthier and exercise to avoid diabetes and stuff. But people don't. And asking what people need is a loaded question as well, since people don't "need" anything. You might need things to live (you classic food water shelter), but some people might not want to live - think physician assisted euthanasia.

Ans as to points 1 and 2, those people are not your target customer.
