Yeah hard to feel sympathy for anybody complaining. So, that lady will be selling her place? Inventory is already increasing.
If I was a host, I'd be worried about operating around the law. Making illegal moves gives up your leverage with guests. You want to charge them an extra cleaning fee? You want to charge them a late check out? Well, they might report you if they feel burned and don't plan on staying with you again. No accountability when you work around the law.
The hosts complaining about overall tourism plummeting are grossly overestimating their value. Tourism is 21% of our GDP (WashPost, 2017) and Airbnb rentals that don't qualify under the new law are a tiny fraction of that. When their units go off market, those visitors will just stay somewhere else (legal airbnb, hotel, etc).
