Why is there no global lost and found with a viable business model? "i will not promote"

This could be crowdsourced on both the lost and the found side with collaboration over time with police departments, USPS and other ubiquitous public services for dropping off/collecting lost and found items. Rewards could be offered with a fee taken by the L&F service and public service departments, great for the environment and create a lot of feel-good moments. Seems very easy to build, thoughts?
