The goal of rent control, as I infer from the mechanism, is to prevent existing tenants from being priced out of their current homes (eventually leading to eviction) - at least as I have seen in the US.
If the goal were to prevent rents from rising, the mechanism would do so directly, ie. regulate all rent, rather than limiting to continued rentals on certain types of property. Which would by definition prevent rents from rising, presumably along with other undesirable effects.
Anyways, the whole issue with conflating "bad" with objective consequences is the "presumed goal," which is of course totally subjective.
