I don't think that's the premise of this post. I think the post is talking about people struggling with adhd, who's symptoms & struggling are being ignored just because they've somehow managed to keep up good grades.
They might also be "gifted" which helps with getting good grades up until some point when it all falls down, as it all just is too much. Also the responsibility and work on other areas of life start requiring the limited capacity to focus and execute necessary home upkeeping, studying & all the other things in life.
Getting the needed medication or even just the diagnosis and the understanding of oneself that comes with it can save a person from a lot of unnessecary suffering.
In my opinion life not being 100% free of inner conflict vs life being full of it are very different things.
The goal being inner peace doesn't mean that one thinks absolute inner peace is possible. At least I tend to reach a bit higher than what I'm only happy with.
Some might, but many do not. Constantly burning out, knowing that you're underachiving (even if other do not see it) and struggling with handling it all can and does make people end up depressed, extremely anxious and even suicidal. If one doesn't get the help they need, many doors can close even permanently.
Some people really need the medicine to function.
Wouldn't disabling JS using something like u-block origin already do that ?
