Well, we need to be fair here. Simply because something is different, it's not automatically "progress" nor "innovation".
The lodging industry has quite a lot of regulations, put into place to protect the consumer. Airbnb kind of currently operates all on their own. You have no guarantee that you're sleeping in clean sheets, you have no guarantee that carbon monoxide detectors are working, etc.
Of course simply because regulations exist doesn't mean every lodging provider adheres to them the same - but it does provide recourse if caught. Applying the same regulations to Airbnb seems to be a net win for everyone involved (except Airbnb themselves).
