How does Sandbox land work?

Could you elaborate on how the Sandbox land mechanism operates? I'm particularly interested in understanding the economic incentives behind land ownership in the Sandbox ecosystem. How do landowners benefit from their investments? What kind of rights and privileges do they enjoy? Additionally, how does the land ownership structure contribute to the overall growth and sustainability of the Sandbox platform? Your insights into these aspects would be invaluable for those considering investing in or developing within the Sandbox ecosystem.
