So it's defined as policies expected to produce affordable housing, whether or not housing turns out to be affordable under those policies. And it's not affordable without those policies in place, regardless of price.
It's an old trick. Hayek described it well, way back in the '40s:
> "The most effective way of making people accept the validity of the values they are to serve is to persuade them that they are really the same as those they have always held, but which were not properly understood or recognized before. And the most efficient technique to this end is to use the old words but change their meaning. Few traits of totalitarian regimes are at the same time so confusing to the superficial observer and yet so characteristic of the whole intellectual climate as this complete perversion of language."
