I think you'll find that you're amongst friends here.

My advice for Stacker News users is to zap big and zap often. The site divvies up a rewards pool everyday and zapping content you like generally more than pays for itself. Win-win.

>bitcoin in a post-apocolyptic world 

Almost impossible. In a post-apocalyptic scenario:
1. Communication worldwide will be fucked up and that means: vrey few miners, very few nodes.
2. Electricity is really scarce or not existing at all. Maybe you can start with solar or hydro, but that means you need materials that are really scarce.
3. In a apocalypse situation your priority is NOT your bitcoin, but food, shelter, security. To obtain these, will be other more type of money, like batteries, salt, water, gas etc.

IMHO Bitcoin will not be a priority in such scenario, you will have many other more important priorities.
So we should focus more in how to MAINTAIN the existing status of things and make a smooth transition to a Bitcoin world.
