Too critical? or just tough love?

After reading City Comforts Blog, TM Lutas reflects:

I had a great flashback reading it as it's quite critical of the right wing and libertarianism as having nothing original of import to say on the subject of creating livable urban spaces, a criticism that used to be very common about conservative urban policy. Well, conservatives, no doubt tiring of the constant ribbing, eventually did get an urban policy and lo and behold, they started getting elected in major cities as their ideas looked pretty good compared to the liberal ones that had failed so obviously in cities across the US.

I didn't mean to be critical; I call it "tough love." Yes, I am throwing out a challenge of sorts. And I assure you that I would be delighted to hear practical, conservative alternatives which do not deny the goal of humane urban form as a way of achieving it, if you follow my drift.
