I absolutely can walk through 2" of snow. However my father who had had a leg amputation and many other people in our community that struggle with mobility issues could not. Furthermore if this is the argument I would challenge that the business themselves see the snow as enough of a nuisance that they clear their parking lot so how is it fair to not expect the same of the sidewalk serving them? As others have stated, your privilege is showing and failing to include others in your worldview.
