Okay, equally unpopular retort: not all of us work within 2, 10, or even 50 miles of where work. Shall I walk 25 miles round trip every day? Should I grow hydroponic gardens of rabbit food in the winter? Should I just walk south across the border and demand my right as a human to displace others so I can soak up the sunlight and reap the benefits no one on the planet is owed?
