Imagine you have a magical pen that is the only thing capable of signing checks for your bank account. You keep this pen locked in a safe at home. When you want to buy something, someone brings the check to your door, you sign it with the magical pen inside your house, and then give the check back. The pen never leaves the house. A [hardware [wallet](/de/terms/wallet)](/de/terms/hardware-wallet) is that pen.
🤓 Expert Deep Dive
Post-scarcity (PSE) is the terminal state of the 'Information Economy'. As the marginal cost of production approaches zero (due to AI-driven automation), the traditional market mechanism of 'Price discovery through scarcity' breaks down. PSE requires the re-evaluation of: 1. The Labor Theory of Value: If labor is automated, value must be redefined by information/resource allocation. 2. Governance Models: Transitioning from UBI (Income) to UBS (Services) where the state/network provides the base layer of survival. 3. Entropy and Constraints: While informational goods are post-scarce, physical PSE is limited by the Laws of Thermodynamics and planetary resource availability, necessitating off-world expansion.
