I mean, I don't necessarily disagree with the first part of what you said; if I had e.g. depression I wouldn't want to take any drugs myself, because I'd be too afraid of the side-effects. Still, by denying or downplaying the biology involved we're doing ourselves a huge disservice. Just take Mikhaila Peterson. Auto-immune problems, depression etc. all seemingly connected to some real weird gut microbiome phenomenon. It was never about changing the world-view in her case, it was just about changing her diet.
But in her case, imagine that she had no intent on changing her way of thinking and behavior. If she just insisted that she should do nothing different, but be given the pill to make her condition go away. In fact, that sort of what is what happened with her as a kid, with the initial diagnoses and the poor results it gave her. All the anti-inflammatory drugs in the world could not help. Only once she started to think about the "problem" in a different way and changed her conceptualizing of the nature of the problem and her behavior, was she able to change the outcome. See, she actually took control over her own health, rather than being a victim and demanding a pill to stop it. So, I don't think your example proves your point, in fact, really just the opposite.
I mean, I see what you're getting at but no, haha, I don't agree. She didn't 'will' her condition away, it wasn't about world-view or having a positive outlook on life, it was about physical illness caused by some weird digestive shit. I agree that the drugs didn't help, and in that case you do what you have to do (been there myself, googling, experimenting with my own solutions when the doctors and the pills kept not improving anything), but I don't think this has anything to do with 'control'. Just because something is not in your control doesn't mean you have to lie down and be a fatalist victim, I mean, why should you? On the contrary it can be a liberating experience since you don't have to feel guilty about not 'controlling' your life the proper way.
If the way you think causes problems, all the drugs in the world won't work. If the fundamental problem is just a biological mis-working, then sure, it can work to just take a pill. My hunch though, is that there are far more people in the former camp, than in the biologically malfunctioning camp.
But are you sure of that? And what of everybody in between, who need that joint therapy?
If fact, I think many people with poor health, are in this camp. They don't want to stop eating bad food, they don't want to stop over-eating, they just want a pill to make these things have no consequences. It seems plausible that it could work the same sort of way psychologically for a variety of issues, in many cases.
I just don't agree here. I don't think anybody actually wants to be a fat fuck. They might rationalize it (because they're in control of their lives after all, aren't they?), but I don't think anybody genuinely wants to be stuck in these unhealthy behavioral loops.
