What causes depression during lockdown? Is it lack of exposure to sunlight? Is it lack of exercise? Is it eating more poorly? Is it people being confined to spaces that may not be that clean that they normally leave during the day, thus exposing them to more mold and germs?
It isn't necessarily dystopian. It may still be a valid and genuine treatment, though I agree it would be better to understand more thoroughly why it works, not just that it works.
A former medical professional once told me "The answers you want for how this OTC drug works at the cellular level don't exist. That isn't actually what drug studies cover."
I don't disagree with your aims. I simply disagree with some of your implicit assumptions.
I'm not depressed. I'm a brunette for the first time in a decade or more. I live without a car and the sun typically keeps my hair bleached out to a shade of blonde.
But I have a serious medical condition and already did remote work and germ control is my life.
I had a longstanding issue resolve about six months. For the first time in decades, I'm mostly not suicidal anymore.
To whatever degree depression is biological in origin, drugs may be a reasonable treatment.
Granted, curing sick building syndrome and other root causes may be better in the long run. But it can take ages to confidently identify such things, educate people, find solutions, etc.
In the mean time, a new drug option for a biologically based ailment may do wonders for people in the here and now.
I routinely treat somatopsychic issues with diet and exercise. I also routinely get dismissed by internet strangers as a nutter.
So I'm confident that the answer you want both exists and will take an excessively long time to distribute to a meaningful portion of the human population.
I don’t want to live in a world where the cure to depression caused by forced lockdowns is to take psychedelics. That seems very dystopian.
