Strongtowns has an article on this [1] that cites papers which show that increases in walkability lead to higher home values and attracts more businesses. If you have studies that demonstrate an effect and a model which corroborates the effects, opposition is necessarily irrational. The fact is that in NA people are very attached to their cars and parking and that people in NA are much more "fitness inequal" (people who are unfit in NA are much more unfit than unfit people in other developed countries) [2] so it's much more likely for folks in NA to oppose anything that takes away parking.
