I was one of the 9% that said I would feel comfortable receiving food stamps and remain early retired. However, for me, the odds of those two events ever happening concurrently are near zero, since to qualify for food stamps you can't have more than a few thousand dollars in assets, and income can't exceed a very low threshold. And if you have almost zero assets and almost zero income, you probably won't be early retired for long.
Maybe if you can get all your assets into Roth IRA's and Traditional IRA's and those accounts aren't looked at as assets for food stamps, you could have a really low income and still get food stamps. I assume at some point you are cutting off your elbow to spite your thumb.
I'll note that my investment portfolio is more than adequate to cover our projected living expenses indefinitely, so I'm not going to go out of my way to ever use food stamps, but I don't think it would be wrong if I legitimately qualify.
