- In-game money can be obtained through mining natural resources. These resources are rare
- Free market
- Physical delivery of items will absolutely be required
- Probably some sort of Uniswap-like AMM, running in different market hubs
- Property: no property rights coded into the game; whoever has de facto control over a piece of land "owns" it. Different states can define their own property rights & have their own property registries, enforced by their own police.
