Yeah, that makes sense. This all tracking with my examples and I’m pretty sure we agree here! Is this person awake or not? Is informed consent required when delayed treatment would be dangerous if the person came in in an alerted state, comatose, etc.? Being voluntarily intoxicated to the point of being a danger to your own life gets your consent ignored in many cases because most of the time society won’t allow a person to just die.

I think I take your point about consent being not just sex in that context, but the medical version doesn’t really apply here.
