They aren't saying affordable housing isn't needed. Just that the method for making housing affordable shouldn't be trying to make the current housing supply cheaper.

And from this is where you get "rent-control is a terrible idea". Essentially: trying to artificially drive down housing prices in any way is generally inadvisable if you can just build more housing.

Sure that's technically an opinion, but it's one based in facts, and it certainly doesn't have "zero evidence".
