It's an interesting sentiment but it really isn't practical. There isn't enough local product to feed the kinds of populations we have anymore. At the rate cities are gobbling up surrounding farmland there will be even less as time goes on.
It isn't practical because we make it impractical.
Many studies have shown the viability of large scale, vertical farming for urban centres.
Although...we might all have to become vegetarians to make it work, unless they figure out vertical animal husbandry
