"Time since roast" is hardly the only reason to prefer locally roasted beans. Actually, it's not a good reason at all, since you can ship roasted beans across the country a few times before they're ready to be ground and brewed.
Some folks just like to support their neighbors, and buying from local roasters could also mean fewer shipping miles (and less carbon emissions) attached to that that bag of beans.
