Getting around regulation isn't, in my opinion, the takeaway for AirBnB and Uber from a platform like Steemit. The real lesson is: the rent-seeking behaviours of monopolistic platforms are vulnerable to disruption by a platform that is owned and operated by the people who make up the network.

If you think about how Uber gained market share, it was by attacking the rent-seeking behaviours of existing taxi firms (medallion restrictions etc). But, now, it's vulnerable to something Steemit-like for cars: why pay 20% of your earnings to Uber, when you can own a chunk of the network and not pay that 20%?

Steemit looks to me something like a 'guild for content producers' where you can buy influence - I think Uber and AirBnB will eventually go the same way.
