[Borderlands] How does a functioning economy even exist?

So the Digistruct is apparently able to make anything without limit. How exactly does money still exist? It's not like this is a special new tech because it's so deeply engrained that even the worst, most uncontrollable planet in the known universe has it. And why does Scooter have a garage to repair vehicles that shouldn't need to be repaired?

Hyper-controlled 32,768-bit DRM keys for anything that can be digistructed, selling an item also sells your DRM key for that object and purges it from your local hardware.

[A lot of this also comes down to game mechanics, the respawn mechanic for example is also not a canon thing in the setting.]
