Hard to imaginate that money wouldn't be ever invented. It was invented long time ago in many areas independently so it is probably almost ASBish that there wouldn't be money.
Agreed.
If you organize for projects (so if you're doing agriculture, having long term larger-than-family-sized wars, holding regional religious events) you need a mode of accounting. It might not be how we discuss "money" colloquially, sure. But fundamentally? That's money.
No real way around it.
Cowrie shells would remain the preferred medium of exchange. I think I'd take up mollusc farming.
Cowrie shells were money though. They just weren't post-bullion money, usually.
As an addendum, money not existing does not make everything free. It just means that either another medium of exchange is used instead (cowrie shells, brass rings, whatever) or barter is used.
Yes and no.
Yes, it doesn't make everything free.
No, it definitely does
not mean that either another medium of exchange is used (not in the sense you're using "medium of exchange" anyway), or barter.
Starting civilizations all had means of accounting and systems for distributing goods that functionally were "money" in the abstract, but did not involve a physical medium of low intrinsic value that was culturally/cognitively imbued with value and physically exchanged for products or services. Which is to say no cowrie shells, or copper cards, or brass rings. It was perfectly possible to run a complex urban society in this way.
Take Sumer, for instance. The economy was debt-mediated. Precious metals were a sort of foundation of accounting, but were a medium of
measurement, not of exchange. At the state level this translated to temple reserves of silver ingots used as a basis for issuing loans and mediating budgets between parts of the government, religious establishment, and managerial aristocracy. But until much later periods when treasuries were pillaged in warfare, those silver ingots very rarely moved an inch. The transfers were on paper.
Well, on clay.
On the private level, the same fundamental system was playing out. People carried precious metals with them about their business, but not as a medium of exchange. Rather, the gold/silver/copper/whatever was usually in the form of jewelry, and functioned as portable collateral; a statement of the bearer's ability to make good on loans. It was the distributed mental-and-written (so virtual, sort of)
accounting that was the "value" in these people's lives. There was no need for constant exchange of physical representations of this value, not in a functional society.
Cash and bullion as money are more powerful - they retain their value when no one trusts anyone. The weakness of debt-moderated money is that it requires a level of trust that one will be repaid.
And barter.... Argh. Historically barter seems to be the resort people turn to when they're
already accustomed to an economy based on a medium of exchange, and then that medium runs out. The idea that barter evolved into premodern and modern economies was hypothesized by economists, not discovered by historians.
