Ownership is implicitly treated as reversible - an investor can enter and exit positions with limited structural consequence. This assumption is often incorrect. There are cases where an asset continues to perform, markets remain functional, and yet the owner becomes increasingly constrained.

We can model volatility, discount cash flows, measure correlation, optimize liquidity, and structure allocation with mathematical sophistication. Yet when confronted with a more fundamental question: why some capital structures endure across generations while others fragment within decades, our analytical vocabulary thins rapidly. Why
