A devil's advocate take on your approach (I don't know what I agree with here, but am willing to discuss from this POV):
There are situations when it's generally believed that the person with the skin in the game makes worse choices than someone without. I think the medical field believes that strongly: treating one's family or oneself is considered unethical in most circumstances and always discouraged. Performing noninvasive "fishing expeditions" for problems that show no symptoms is generally discouraged (except some cases where we encourage it for patients from some demographic), lest false positives cause patients to strongly wish for treatment.
All these examples suggest that people with more skin in the game might be over-eager to do something instead of nothing when a choice with unclear calculus of benefits appears. However, we are in a more confused situation regarding war: conscripts have much more skin in the game of war than in the game of suffering from consequences of not entering a war. From a purely selfish point of view, if a war can be avoided by means that cause the same amount of suffering by means other than military, all the conscripts should vote against it, because the suffering will be distributed among the whole population.
I don't think these two problems cancel each other. Each of them is a problem of biased noise, and even if the magnitudes of both are similar, they are likely far from anticorrelated.
> when the deciders who profit do not suffer any risk -> pump and dump, military industrial complex, investment bankers who get bailed out, etc
Agreed about this part, thinking about previous two still.
> as far as i'm aware it's not considered unethical to give medical advice to your own family.
An AAFP journal recommends to do this only as a last resort: https://www.aafp.org/journals/fpm/blogs/inpractice/entry/friends_and_family.html
AMA says that one should not do that except in limited circumstances, albeit giving many more reasons not to do so: https://www.ama-assn.org/delivering-care/ethics/treating-self-or-family
> it's forbidden to prescribe pills to *yourself* though
I don't think it's actually forbidden, except maybe for things that are known to be addictive when used normally. IIRC doctors in Poland are allowed to write a prescription for themselves. I don't know what the medical board says about ethics of doing so, though.
