+## Assets Can Be Productive Or Passive
+### Status: Training Corpus Seed
+### Layer: Layer_0--Primitive_Facts
+### Purpose: Teach that an asset may matter because it produces capacity, income, access, or collateral, not only because it can be sold
+### Repository Path: docs/training/corpus/Layer_0--Primitive_Facts/CORPUS-0021-assets-can-be-productive-or-passive.md

+## 0. Principle
+
+An asset is not always valuable because it can be sold.
+
+An asset may be valuable because it produces:
+
+- movement capacity
+- storage capacity
+- work capacity
+- rental income
+- access
+- security
+- collateral
+- bargaining position
+- future opportunity
+
+Some assets are passive until sold.  
+Other assets produce value while retained.
+
+---
+
+## 1. Roman-Visible Example
+
+A trader owns a cart.
+
+He may sell the cart once for coin.
+
+Or he may keep the cart and use it to:
+
+- move his own goods
+- hire it to others
+- reduce transport cost
+- secure better timing
+- carry return cargo
+- support future ventures
+- pledge it as collateral
+
+The cart is not only a sellable object.
+
+It is productive capacity.
+
+---
+
+## 2. Minimal Asset Structure
+
+An asset should be evaluated by at least:
+
+1. physical form
+2. current owner or controller
+3. usable capacity
+4. income potential
+5. maintenance cost
+6. risk of damage or loss
+7. convertibility into coin
+8. usefulness as collateral
+9. ability to create access or reduce cost
+
+Sale value is only one part of asset value.
+
+---
+
+## 3. Incorrect Modern Assumption
+
+Incorrect assumption:
+
+> An asset's value is only what it can be sold for today.
+
+Correction:
+
+> An asset may be more valuable when retained and used to produce future income, access, or reduced cost.
+
+A cart, tool, storage right, or building may matter more as capacity than as immediate coin.
+
+---
+
+## 4. Simulation Use
+
+This principle supports:
+
+- carts
+- tools
+- ships
+- warehouse space
+- workshops
+- land
+- buildings
+- rental income
+- productive equipment
+- collateral
+- maintenance cost
+- capacity planning
+
+The model should not treat every asset as inventory waiting to be sold.
+
+---
+
+## 5. Canonical Test
+
+If the model sees:
+
+> The trader owns a cart.
+
+It must ask:
+
+- can the cart move goods?
+- can it be hired out?
+- does it reduce future transport cost?
+- does it need repair?
+- can it be pledged?
+- does owning it improve timing?
+- would selling it create coin but reduce future capacity?
+- is it more valuable held than sold?
+
+Only then can the asset be evaluated.
+
+---
+
+## 6. Success Condition
+
+If the model stops treating assets only as saleable goods and starts asking what capacity, income, access, or collateral they produce while retained, this file is functioning correctly.
