I really liked the view of the article. However it's assuming one thing that's not true for every on-demand or p2p service marketplace: the service provider is a "pro". I'm co-founder of a p2p marketplace for dog sitters and dog owners and most of our sitters are not "pros" (as in people who do it just for money and full time). IMHO that's the basic difference between a truly sharing economy platform and just an "on-demand service". These two kind of companies tend to fall under the same umbrella, often because the ones that are just on-demand services use the "sharing economy" label to protect themselves against regulators.
