Introducing a new local currency after an event

[Skvez]

Money has been around for a very long time.
But to go back before money you go back to a culture where people possessed very little and could carry the few tools/items they owned.
I don't want to go back to that point, it's accompanied by most disease being incurable and a life expectancy in the 30s.

Money is a means for us to do a trade when I have something you want but you don't have something I want of equal value. Without it trade hugely reduced. Much trade allows us to specialise, which while it has some risks, allows us to focus on things we are good at (and hopefully enjoy doing) and makes all of us more profitable than if we each tried to do everything.
