As someone who went bald before I was 20 (Like you it sounds like), I'd say you're heavily generalizing. Sure, shaving your head worked for you and solved your problem, but that doesn't mean it is a solution that solves the problem for everybody, and claiming that it's not a "real" problem because you found a solution that works for you is a bit ridiculous.
It's easy to say I should just completely shave my head and ignore what others think of me, but for me that's not a solution that has worked - it would be great if it did and I could just will myself to stop being self-conscious, but that hasn't worked that well for me. And if a "cure" for baldness would fix my problem then that's useful to me and a solution to a real problem I have - and it is something that would certainly improve my current quality of life.
