I suppose obesity could be considered a handicap.

Having problems walking is having problems walking. Judging the disabled because you think they deserve it doesn't make them healthy again. I'm not sure what it accomplishes, to be honest.

Scores you some point of self-esteem, if you're the kind of a person who bases their worth on comparing themselves with "those others".

I think the idea is that you can have problems with walking that could be fixed by walking (I am currently in a situation like that after a knee surgery). I cases like that, this would not be a (objectively) helpful device.

But I do not consider myself qualified on this topic, as I have no idea how far the obesity problem has gone in the US.
