@nihilist: you hit on a major point imo, regarding what happens should you get sick. going into a hospital is basically saying goodbye to everyone you know, unless you recover and are released as "virus free". not the way i want to die, for sure.
@metalist: sorry hear that your relations there turned out to be so unreliable. that, in my experience, is the case everywhere. especially in a city, it is easy to form shallow (if useful, even fun) relations, and difficult to form deep, trusting relations. yet it can be easy to conflate them.
one thing i did when assessing various scenarios (particularly worst-case scenarios) coming out of something like this, is to think really hard about what is truly important to me in my life. (of course i did that long ago, leading to my leaving urban life forever, but always good to re-assess). the first thing i always come to is: i want an easy, reliable way to end my own life when i choose to. after that, i think about survival without the state and economics.
