I'm all for the direction that drug policy is going (towards more treatment, less prison time - I live in Oregon and we're on the forefront of this in the US) but I'm not sure how this would work in regards to misinformation. How do we get conspiracy theorists into treatment? Won't they just figure that's part of the conspiracy to re-educate them? And a lot of this disinformation is coming from bad actors with intent to harm.
The epistemic gap is, I think the most serious problem we face now. We can't address other serious problems like climate change or even getting COVID vaccines out to people because there's disinformation. We seem to be completely unprepared to deal with this. The immune system offers an analogy - we need a societal immune system that attacks disinformation in some way. No idea how we get there, though.
