If I were supreme leader? Both of these models create a tragedy of the commons of sorts and meaningfully distort incentives. So I would have the tax revenue go to public good like universal health care. Again, not a policy that could ever occur but it would be great to raise funds for something positive while incentivizing business models that actually charge for value. It would be good to stop advertising be strapped into previously purchased products or subscriptions, or stop incessant stalking for attribution of sale.

As for short term rentals: the first time the housing market was financialized the economy crashed. People with money bought up all the pieces and are ransoming back what used to be the American dream. You pay money for a quasi-luxury experience and in reality you fund airbnbs profits and become an employee in someones REIT and are fined for the pleasure.

Not totally serious, but not totally unserious about it either.
