Not mentioning a solution but a deeper dive into unintended consequences.

NYC and Boston are large cities. As far as I know, there were fewer tenant protections enacted in Boston and overall, rent has not increased as quickly.

More protections seem to protect bad actors and also has a disproportionate impact on smaller owners who cant absorb the costs.

Small owners leaving the market seems to create a larger problem of consolidated ownership/ fewer players, which leads to higher rent .

If my logic is wrong please let me know. Property in NYC is expensive and renting your property carries risk. Having tenants who refuse to pay rent can easily push owners into foreclosure
