The _actual_ sharing economy is great. Your beef is probably with corporations that masquerade as part of the sharing economy in order to exploit regulatory loopholes (e.g. Uber, Airbnb).

For an example of the actual sharing economy: I'm a member of a local cooperative that owns and maintains a fleet of ~3k cars, distributed across the country at most train stations and in many neighborhoods. For an initial deposit of $1k, "my car" is whatever I need it to be at that moment. If I need to transport furniture in the morning, it's a Mercedes Vito. For a leisurely drive in the countryside at lunch, it's an Audi convertible. And for a quick grocery run before stores close, a cheap Citroën C1 will do the trick. And because the whole thing is a cooperative, per-km prices are around what I'd pay if I owned any of the cars myself.

Sharing is great. Regulatory arbitrage masquerading as the sharing economy, less so.
