Sure you can slowly, over a long time, convert already dense areas into being less car centric, but you aren't going to make the rest of the country that way. Parking minimums, when they exist, are set by super local governments, they already don't exist or are set very low in areas of high density. The solution is to increase density, but again you aren't going to do that in the rest of the country. Random bars in Ohio are still going to have large parking lots, because land is cheap and given the choice, most people prefer less density.
