 All right. But what really motivated me to write this book is when I realized there's a lot of other problems that seem unrelated but are, in fact, closely connected to housing regulation. Many of these problems, people think of them as they're so intractable, what could possibly handle any one of them? And I was looking at the evidence saying, not only do I know how to handle one of them, I know one policy that simultaneously make a big dent in a long list of problems.
