Oh come on, the comparison to driving is misguided at best and dangerous at worst.
And what's best doesn't always come down to the individual. That's something I disagree with. Do individuals make dumb decisions? Sure but that doesn't mean it's best. What's best always comes from when humans come together to achieve something. Civil rights, economic rights, human rights all came about from collective action, not individual action though as I said there is value in the individual. That's why individualism is misguided. Now that doesn't mean that whenever humans come together to do something, it's best because horrible things can happen from the wrong collectivist action as well like Nazism or white supremacism.
Others can advise, but it's up to the individual at the end of the day. You can only hope they make what would seem to be the sensible choice, but what's right for them cannot ultimately be decided by others. I'll admit, when it comes to age, the younger you are, the more prone you are to making poor decisions because of your lack of knowledge and wisdom, which is why we label people students, adults, etc. That's far from a perfect system as well though.
Erase Hitler from history. Where does Germany end up? Erase MLK from history. Where do civil rights end up?
Why did others, choose themselves, to follow these individuals example and form a collective?
Freedom of choice vs forced collectivism. Which is worse?
