Exploitation of marginal utility is fundamentally disconcerting, and it should be -- as tech people, we could think of it as being paid for time spent in a chair, or lines of code. It exploits an inefficiency which exists because of an absolute measurement that mis-assesses the situation. In the case of housing, at the basic level, we pay a monthly rate in order to have a place to sleep (and maybe live & eat). But embedded in our rules and laws are assumptions about how that works, and one of those core assumptions is stability (that is, people who make this exchange of money for housing will remain in the housing for longer spans). Our noise ordinances are based on long timelines for investigation, monitoring, and enforcement because they embed the assumption of stable tenancy. Our building codes assume certain occupancies and our maintenance schedules assume certain rates of wear. Our building security practices assume that people with the keys have an invested interest in restricting access. These assumptions may or may not be desirable, but they exist, and because of their existence renting an apartment (I have different feelings regarding owned single-family dwellings) for short-term AirBnB-style rentals violates not only the social contract with neighbors, but the unwritten contract involving a number of ambient practices with potentially negative consequences. I'm not 100% against short-term subletting, and I'm certainly not against having relatives stay over, for example. But this is a classic example of both money and automation fundamentally changing an existing practice -- people are "doing the same thing", but at a scale and in a way that results in an emergent difference.
