Is the housing crisis solvable without radical policy change?

Context

The housing crisis—characterized by soaring prices, limited affordable supply, and homelessness—has become a defining economic challenge in developed nations. Policymakers debate whether incremental reforms (zoning adjustments, tax incentives, public-private partnerships) can solve the problem or whether fundamental restructuring (massive public housing investment, land value taxation, rent controls) is necessary. The question hinges on whether market failures require radical intervention or whether existing tools, deployed more aggressively, suffice.
