I don't see any reasons why a single one of the policies mentioned in the article would "strengthen growth". Economic productivity is not increased by changing the quantity of money or lending, arguably the opposite as it increases uncertainty, and the judgement of a handful of people is in the long run less accurate than that of the market as a whole.
There is also a serious confusion between "growth in the next 12 months" and long-term growth, obviously the latter is the important number. The article encapsulates what is wrong with thinking about central banking in general, the last bastion of the folly of central planning.
