The article is essentially about tax authorities trying to offload their work on AirBnB. Irresponsible owners will not disappear if it happened.
I'm sure local governments would love to collect a big check from Airbnb instead of hunting down thousands of tax-dodgers; but doing local tax collection authorities' work for them isn't exactly Airbnb's responsibility.
Not by default, sure, but nothing prevents a local government from creating a law that says, "where an organization takes commissions in connection with its marketing and/or or the facilitation of payment for short-term rentals of property within our jurisdiction, the organization is responsible for collecting any occupancy taxes associated with the transaction."[0]
