I actually don't see how you could unironically argue against providing essential foods (think bread, beans and chicken/fish[whichever is local]) free of charge, basic income style.
If that's affordable, we should totally do it. Of course, affordability is a key part of the equation. I don't know if a basic sustenance program is affordable. I do know that basic sanitation is /totally/ affordable.
Also, I feel compelled to point out that there's a public health interest in making sure everyone has a sanitary place to defecate. Societies that failed to provide this were regularly ravaged by cholera.
