Outside of split ownership, the word "sharing" becomes a bit of a misnomer. What Airbnb or Uber does is not sharing in any generally accepted sense of the term.

Outside of split ownership, the word "sharing" becomes a bit of a misnomer. What Airbnb or Uber does is not sharing in any generally accepted sense of the term. That is to say, these are not co-ops in which the owners and the users are one and the same. Rather, they are creating a market for very short-term sublets. There is precisely zero sharing involved. And that's just fine. In terms of producing greater efficiencies from a fixed stock of privately held material resources, this approach can be a very good thing. However, you have to be careful when dealing with people who are too nervous or deluded to be honest about what they're actually doing, and who opt for a thick slathering of bullshit instead. It would be wise to ditch the dishonesty a.s.a.p. Sticking with it runs the risk of being disrupted by organizations that can deal with regulation more effectively thanks to greater comfort with general transparency and basic integrity.
