I mean, you could ask the same question for a race-based test, and come to the same basic conclusion: that it is "irrational" to prevent it.

I think you have to leave look a little deeper to reach a correct conclusion. Namely: I don't think significantly more free housing would in fact be offered without these regulations. So it would not be rational to allow this type of discrimination. The regulation in essence provides an anchor "price" for free housing, while not distorting the "market" very much. This is a good type of regulation to have.

You are confusing housing with homeless shelters.
