There's absolutely nothing wrong with pointing to empirical evidence to support a claim (in fact, that is an excellent thing to do!). The issue I have with the original claim is that it isn't proven that giving away housing is a cheaper long-term solution than other forms of welfare. I certainly don't think we need to wait until something is proven to have an opinion or move forward in trying to make the world a better place (if we did, we would never take action in most cases), but we shouldn't present research in a way that disingenuously overstates our knowledge.
