Years of the cumulative impact motion on the joints from walking and running exercise take their toll on joints, meniscus, tendons, and the rest of the muscular exoskeleton. The cumulative impact is mitigated by asphalt (road) versus concrete (sidewalk). An exception to this would be some of the UK roads where they use the rock that we use to surround railroad tracks. The rock is leveled but floated to the surface, so in effect you are running more on granite than on asphalt in Dublin.
Long term and long distance exercises are better served by exercising on the "softer" asphalt over time. Dirt is better, but the inherent unevenness and pebbly protrusions can negatively impact one's ankles, knees, toes, etc.
So yes, the walker is better off on the softer road than the harder concrete. A short and occasional walk to Publix will probably have no quantifiable difference, but if you regularly run or walk 25-50 miles per week, then yes, there would be a difference worth pursuing.
FWIW.

Absolutely correct. I have run multiple marathons (now have a knee replacement
and we always avoided sidewalks. Asphalt/dirt were much easier on the joints.
