"What they should or shouldn't want" is already deeply influenced by housing policy. Cheap suburban homes which don't fully pay for their externalities are one result of this housing policy, and children grow up accustomed to this bizarro-world reality where increasingly tank-sized cars (this is—astonishingly—not even hyperbole) are the only practical means by which one can go from Point A to Point B.

Meanwhile people in Europe live in denser areas with smaller, more fuel-efficient cars or where they can do most of their commuting by foot, bike, or rail. That is the norm for people from those cultures, and so they—like us—largely choose to continue living in a world similar to that in which they grew up.

Given that one of these modes of living reliably produces a happier population and is significantly more environmentally and economically sustainable, that we're already in the business of promoting one style over another via housing policy, and that one of the core purposes of cooperative government is to find ways to promote outcomes that benefit everyone despite going against individuals' self-interest… what on earth is the problem?
