I mean, in the interest of needing to stay safe, to not attend or orchestrate too large of gatherings, and the need to isolate from friend-hangs in between immunocompromised in-law visits.
I’m already somewhat isolated living in a suburban area over an unaffordable city, friendly with my neighbors which is nice but I’m too old to bond with the young’uns and too weird to bond with the olds 
Trips to a friend’s cottage are lovely, of course and are a great recharge. But I don’t think what ails my attentions would be resolved by only living remotely.
IDK, I don’t think it’s a terrible idea, but would come with other tradeoffs and it’s already more difficult to herd kittens into the same physical space!
Their argument may be more an implied riff on the saying
if you’ve met one non-neurotypical person… you’ve met one non-neurotypical person.
and not wanting persons to speak overbroadly on culprits, cure-alls, and causality.
Not so much them stating that what worked for you didn’t and doesn’t work for you, but that others who have found less success are failures at somehow more obvious alternatives to medication or medicine period over some spectrum of laughably simple to extremely difficult for many lifestyle changes.
And with regards to non-NT a sort of “what do Doctors know, anyway?” tends to be a common refrain against the advice of better Doctors and less helpful to improving the state of medical care.
Rejecting the possibility of more humane care to how you function outright limits society’s interest in treating others better, encourages less concern with improving the medical system, and introduces the possibility of quackery.
Again to clarify- not saying that’s what you’re doing here, but why making a more naturalistic approach to objectively difficult problems the default option can be taken poorly.
People have certainly suffered as much by laypersons diminishing their experience under the guise of “helping” as any uncaring medical doctor.
Self-help peddling is different from “peddling drugs” but when one provides an effect and the other does not, telling others to they need to pre-emptively reject valid options for treatment is going to go over poorly when they’re already having a hard enough time navigating society.
