Sine you mention it, I feel obliged to point out that the only project that seems to be working on a real alternative to the sharing economy giants right now is Swarm City, a distributed application built on Ethereum (https://bitcointalk.org/index.php?topic=1794644.0 https://bitcointalk.org/index.php?topic=1794644.0 for information post). Despite the current ICO craze, most of the funded projects don't seem to be working on problems that affect everyday people with the exception of a few select projects. Disclaimer: I'm a backer of the Swarm City project, but outside of that I truly believe that dApps that are able to solve the problem of sharing economy businesses built on privately controlled infra maintained by corporations completely financed with massive amounts of VC funding do not have correct incentive alignment with the providers of services or the users of the services, which makes exploration of alternatives a moral and social obligation.
