also just as importantly (or moreso for cases of individual rooms used for social/hobbyist clubs like this) would be 'empty building taxes' to prevent the eventuality of landlords preferring to rent out fewer properties over reducing the cost of vacant ones because * housing is necessary for survival so people cannot afford to baulk at the prices of artificial scarcity, making the optimal price effectively arbitrarily high without regulation * landlords are generally not infinitesimal entities in a vacuum, and generally stand to lose existing customers who are still on the expensive contracts if they cheapen their unoccupied offerings although such a solution would just move the problem one layer further up (stop building properties to have them be vacant) and the solution is land tax
