That's a deeper / secondary result. I was thinking in terms of basic needs. Self-reliance is good, but if you live in a good area, close to a good hospital where you don't wait and don't need to worry that calling an ambulance is a debt risk, your survival chance is much higher. You can't realistically provide this yourself / in small community.

Even basic human events like a childbirth: if everything goes well - great, if you get PPH - you've potentially got minutes before bleeding out.
