 Still, there may be some actual or potential win-win scenarios cases where promoting a particular form of communal life can promote, rather than undermine, other forms—and political communitarians will of course favor change of this sort. For example, critics have objected to residential community associations, or “walled communities”, on the grounds that they undermine attachment to the polity at large and erode the social cohesion and trust needed to promote social justice and sustain the democratic process (McKenzie  1994).[15]  Might it then be possible to reform urban planning so that people can nurture strong local communities without undermining attachment to the national community, perhaps even strengthening broader forms of public-spiritedness? Many practical suggestions along these lines have been raised. Architects and urban planners in the US known as the New Urbanists, for example, have proposed various measures to strengthen community building—affordable housing, public transport, pedestrian focused environments, and public space as an integral part of neighborhoods—that would not have the “privatizing” consequences of gated communities. The problem, as Gerald Frug points out, is that “virtually everything they want to do is now illegal. To promote the new urbanist version of urban design, cities would have revise municipal zoning laws and development policy from top to  bottom.”[16]  This points to the need for public policy recommendations explicitly designed to favor complementing forms of communal attachments.
