I have human hiveminds populating the various landmasses of Earth. A Hivemind is one giant mind formed from the mental aggregation of every human that makes it up. This singular but powerful mind can pilot every body it has with absolute ease, able to perfectly coordinate its bodies much like a human moves its fingers. A Hivemind can also comprehend and 'feel' every sensory data its bodies receive without getting overwhelmed by the sheer information. Essentially, think of it as one individual in multiple bodies.
Hiveminds occupy specific parts of the world, forming what are technically 'nations'. There are thousands that exist usually. Relationships between them are varied. Current tech and civilization level for the Hiveminds is modern day.
Each Hivemind has one 'weak' superpower such as not needing to eat or being able to produce a few grams of any metals out of nothing. Because of how many bodies a Hivemind normally has, these superpowers achieve a qualitative change through immense quantity.
The mental aspect and superpower of a Hivemind is supernatural in nature so it is completely detached from natural processes. Consequently, the humans that make up a Hivemind is physically similar to a normal person.
Under these conditions, would an economy form among the Hiveminds? Would they have a need for it?
