Ignore Dogmen. Aquire iSlabs.
ITT: I'm making a semi-serious proposal that the currency for NEO Scavenger be measured in iSlabs.
Hear me out on this one.
Right now money is this imaginary thing that has no mass, no basis in reality, and no practical use in the real world. Your average thug or caravaneer doesn't know what a dollar is any more than they understand how to calculate the R-Value of the newpaper insulation in their cardboard shelter. Currency really has no value or basis in trade when there is no centralized government to establish & hold its value.
On the other hand, iSlabs are plentiful. They seem to show up everywhere. 99% of the time I discard them. Often I leave piles of the things in my wake after scavenging through small clusters of homes & buildings. They're not exactly common, but they're not so rare as to be unique artifacts. Like artifacts, they are relics of the old world, and as such there is a finite amount of them in theory. Of course, there are actually an infinite amount of them because they are randomly generated on the looting table, but that's not relevent here.
Also, iSlabs are mysterious & full of wonder. Most of them probably have a little bit of power left in them, and will function if you know how they operate. They contain arcane knowlege of the old world, such as the teachings of the ancient pagan dieties known as the LOLcats, as well as the aphoristic proverbs known simply as "memes." They appear to have odd abilities known as "apps" that allow them to do many things ranging from creating light to predicting the weather.
In short, they have no practical value for survival, but they are items that have a definite, tangible value in a non-practical sense in the same way as gold or precious gems. That makes them perfect for barter.
