6. On single-point solutions: "There is no single silver bullet for construction costs because the inefficiencies are distributed across a long, complex value chain." — Source: Construction Physics
7. On the illusion of simplicity: "When a process looks simple, it usually means that a massive amount of complexity has been successfully hidden behind a standardized interface." — Source: Construction Physics
8. On incentive alignment: "You cannot change how a building is framed or wired unless you also change how the local inspectors are trained to evaluate it." — Source: Construction Physics
9. On feedback loops: "Complex physical systems have slow feedback loops, which means it takes years to learn whether a new material or structural design will actually hold up." — Source: Construction Physics

Part 7: Housing Costs and NIMBYism

1. On housing barriers: "The high cost of building homes in America is heavily driven by local zoning laws and the political power of neighbors to block development." — Source: Odd Lots Podcast
2. On local opposition: "NIMBYism doesn't just block projects outright; it forces developers to spend years in design iterations and legal battles, driving up the cost of capital." — Source: Dwarkesh Podcast
3. On land values: "As construction gets more efficient, the gains are often absorbed by rising land values in desirable locations rather than translating to cheaper homes." — Source: Construction Physics
4. On code requirements: "Modern building codes mandate higher energy efficiency, better fire safety, and stronger seismic resilience, all of which add baseline costs to new housing." — Source: Construction Physics
5. On the trades shortage: "The shortage of skilled tradespeople makes labor more expensive, but it also reduces the overall capacity of the industry to build fast enough to meet demand." — Source: Odd Lots Podcast
6. On bespoke planning: "Reference: In the Unleashed episode notes, Potter says construction struggles to achieve economies of scale because buildings are hard to transport, materials and labor remain expensive, and builders face different codes, permitting jurisdictions, and environmental requirements." — Reference: Unleashed episode notes on construction economies of scale and permitting jurisdictions
7. On the financialization of housing: "Because housing is treated as an investment vehicle, there is immense political pressure from existing homeowners to maintain scarcity and protect property values." — Source: Dwarkesh Podcast
