If its about giving the power to seek and provide the service to individuals - like what Uber did - "I can share what I have and I don't need a license for it". Quite known to everyone Uber has built its service base by offering lucrative benefits to its drivers/service providers - one of the many reasons it was able to scale. Effect of that is people are buying new cars at the rate Toyota Vios can't fulfill the demand. Grigi could be free to use for a year like Whatsapp. At the end of the year many who shared their service will have Karma GB in their pockets to trade...at this stage bitcoin gained its popularity.. people had something to trade.
