I used to walk to the grocery store in Germany six days a week with a toddler and an infant and a backpack for my groceries. I was in American military housing.
After I moved to Kansas, I ran into a soldier I did not remember, but he clearly remembered me. The soldiers who knew what it was like to carry a 60 pound ruck sack had all kinds of respect for me.
It can be done. Not by everyone and I am not saying you are required to live that way. But giving other people options doesn't preclude you from driving everywhere. And that's the entire fucking point here.
Feel free to drive. But I like walking. I liked walking even when I was carrying groceries home in a backpack with an infant strapped to my chest and a toddler sitting on my shoulders.
