All those "shareconomy" companies try to portrait themselves as organizing platforms for the average individual to earn a few bucks on the side.
But in reality most of the services are used by other highly professionalized companies that operate outside of any traditional legislation. AirBnB is being used by companies to full-time rent apartments in attractive metro areas while avoiding hotel taxes and Uber is being used by professional drivers that don't pay the usual taxi service fees and/or taxes. Because of that both AirBnB and Uber are cheaper than the traditional hotel/taxi service and take away revenue from the businesses that adhere to the law.
