It may not surprise many of you, but I am a huge fan of the sharing economy. Not only does it allow for greater efficient use of resources, but it distributes economic power more and more to people. Have an extra room? Rent it out for a day or two. Have some spare cash? Fund a project. Have a car and some spare time? Help drive people around. There are many more examples I could cite, but they all have this in common: they put means of production, that is the ability to generate profits, into the hands of people.
These gains are brought to you by capitalism, a system where innovation is rewarded and where people work together for the greater benefit of each other.
In the interest of full disclosure, I have no financial interests in any of the companies I linked to above, although I am an Uber driver.
UPDATE: In the comments, Peter points us to a better way of framing the above argument.
