It reminds me of what happened in my hometown of Austin, Texas when Uber was outlawed for a little while; people started a Facebook group where they just would ask for a ride, and someone else would offer to give them one (for a price). It was kind of like Uber, except way less regulated and with fewer protections for anyone involved.
To be honest, though, "Pure Chaos" in the title seems overstated. The article even admits that hotel prices are expected to go up, which would suggest that fewer people will stay in BnB's.
