AirBNB issues are just an ornament on top of the 3-tier wedding cake of today's housing price insanity.
The bottom tier serving as the foundation of this disaster cake is the idea that a house should not just be a place to live, but an investment that should appreciate over time, and thus that there should be a "property ladder." Huge fucking mistake.
Tier 2 is NIMBYs enacting zoning laws that all have the effect of restricting housing supply, which they have done successfully for decades.
And the top tier with your little AirBNB figurines perched on top is the fact that houses are still mostly hand-built one at a time like it's 1959.
And good luck fixing all this when profiting from runaway housing prices is not only big business, but also a huge fraction of voters have most of their net worth tied up in it. Never before has a speculative asset bubble sunk its claws so deep into an economy and society over such a long period of time.
