If homelessness reflects systemic misalignment, then durable solutions must operate at the level of system design. This chapter explores what it would actually take — financially, physically, and institutionally — to ensure stable housing access across a modern economy.

Contrary to common assumptions, the raw material and construction capacity to house populations in wealthy countries already largely exists. The constraints tend to be regulatory, financial, and organizational rather than purely physical.

The chapter examines emerging models — modular construction, new financing approaches, coordinated service delivery — that suggest the problem may be more tractable than often portrayed. But scale and alignment remain the central challenges.

The possibility raised is provocative but grounded: in many contexts, universal housing stability may be less a technical barrier than a systems-integration problem.
