Do you want a big yard in a walkable community? Can't happen.
But you can't have it! Or, more specifically, if everyone has a big yard the community ceases to be especially walkable. That isn't to say that you can't have developments with yards relatively near to retail, so that there is stuff within walking distance. You can still have corner shops or similar, but having sufficient residential density to support significant neighborhood-serving retail isn't really compatible with everyone has a big yard. Keep your yard! Just understand the tradeoff.
