It's a joke, people
I should think it's obviously intended as a satirical attack on the insensitive people who are worried about how the homeless look to them, instead of the problems the homeless are facing.
Not as a serious way of making money off this insensitivity.
After all, the main reason why people are dismayed selfishly at seeing the homeless about is that they feel they present a risk - the odd one might be an aggressive panhandler or worse. So the last thing one would want is to have one's vision of potential hazards obstructed.
