Give it time, and people will get out in the streets again (terrorist attacks), people will eat meat again (mad cow disease), people will buy cucumber again (killing cucumber), strangers will shake hands again (H1N1 influenza), hell, people will even go visit Chernobyl as tourists.
It's not a "real" issue, it's more of a temporary difficulty. AirBnB's business exists since the dawn of time. A setback, if you prefer.
