The 'This Kind Of Smart, Walkable, Mixed-use Urbanism Is Illegal To Build In Most American Cities' meme serves as a satirical critique of restrictive North American zoning laws, specifically targeting Single-Family Zoning and car-dependent infrastructure. The template typically pairs a photo of a dense, pedestrian-friendly environment—such as a quaint European village, a Pokémon town, or a LEGO city—with the heavy-handed language of urban planning discourse. It gained massive popularity on Twitter and Reddit among the 'Urbanist' and 'YIMBY' communities to highlight how parking minimums and setback requirements make it legally impossible to build the cozy, vibrant spaces people actually enjoy. It effectively turns dry municipal policy into a humorous, shareable visual argument.
