Raising interest rates .000001% would technically qualify as "a step".

So would enacting policies that have technically more than zero effect, but also contain gigantic loopholes (purely accidental oversights, I'm sure) that facilitate avoiding the proclaimed spirit/intent of the policies.

Government is largely theatre, the manipulation of the perception of the public (producing "not to worry!" attitudes among the public if done well). Housing costs have been a MAJOR problem for WAY over a decade (as can be seen in various charts), substantial serious action could have been taken long ago before it was too late, now there are hundreds of thousands if not millions of people (recent buyers) in financial positions that could cripple them permanently, in addition to the MANY millions who remain in the position of likely never being able to afford a home (in a traditional sense of the word, or recommended ratios), or will be permanently poor due to having to spend a historically anomalous percentage of their income to just cover rent and food.
