It doesn't change the underlying issue. The issue is every single one of those rooms available on AirBnB is a room/house not available for long-term rent. And that's the problem. It's just as big an issue that there's 10x more one-bed rooms on AirBnB than there are one-bed places to let.
Imagine if new construction was allowed. Then you could build more, and have both one home for AirBnB and another for long term rent. Have your cake and eat it, too.
1% of housing stock is misleading. Generally speaking, a 3% rental vacancy rate is considered healthy. Effectively, AirBnB is consuming 1/3 of the total available rental pool if it consumes 1% of housing stock.
