What practical change can you make for trauma?
What can you do for someone who is living in poverty? The people who work but can't make ends meet? They can't all just go and get "better" jobs.
The people who live in substandard accommodation. There's a housing crisis. Where are they going to move to.
People who have to deal with chronic physical pain or disabilities.
We would need to form some kind of utopia to address the numerous reasons people take anti depressants. Even then, you couldn't cover all eventualities.
So do we just let people suffer? I don't know anyone who has ever been on anti depressants and chosen to stay on them if they did no good. There's literally no point.
It's great for the people who don't need them. Good for you. Don't try and take them away from the people who do.
