If it were that easy and simple, it'd have been done.
The places where AirBNB and their like are causing problems are not in the places where there's abundant land going, it's in the areas where there's significant tourist demand. This is in the cultural hubs.
People with capital are able to buy up the limited stock of housing and make a lot more money through short-stay, rather than long-term tenants.
This causes major flow-on effects.
Businesses which cater to long-term residents find their customers disappearing, and leave in favour of those catering to tourists/visitors.
The nature of the people in the area change: people in short-term stays are less likely to respect the local cultural-norms like not partying until 3am, or other behaviours.
The people who work in the local businesses, find it harder to do so - instead having to commute from longer distances because they now can't afford the rents/property prices locally.
Knocking down a few apartment blocks and putting in more high-density accommodation won't solve it.
Changes can be good and bad. Without regulation the incentives can hollow out desirable places of all but the richest occupants and tourists. Over time even the rich may leave if the help cannot afford to live or commute to serve them. The end game could be ghost towns or whole communities essentially becoming artificial, amusement parks.
