I get what you’re saying, but parents of ADHD children are looking to help them become adults that can function in society and be independent without the struggles that are often accompanied with ADHD: addiction and self-destructive choices.
A lot of the types of people that you mention — rebels, seekers, misfits — I feel are generally less happy individuals, and might chose a different path for themselves if they had the right opportunities and tools.
Sure they might make life interesting for others, and maybe “interesting” is a word they might describe for their own life. And what often makes them “interesting”, looking from the outside, is that they are addicted and/or self-destructive.
But are they ultimately happy, and is it the life they really wanted for themselves?
That’s what parents struggle with. If they know their child will be happy with addiction, self-destruction, and being “interesting”, maybe it would be easier to not worry about or try to help them with their struggles with ADHD.
But most parents think their children will want a different life, and so they also want that for them.
