The point is that, if limited to a level that just covers essential goods, it won't change their distribution, just their payer. If it did change the distribution of the good, then it wasn't essential (because it's the floor; without it, the consumer of the good would be dead; above it, and the vast majority of people immediately spend their income on luxury substitutes).
That is, to be clear, a much lower floor than what many people mean by "essential," which has undergone a kind of concept creep in modern discussion that, depending on the person, might be a cell phone, to an education at a private university, to owning a condo in San Francisco. My essential here means enough to afford enough caloric and nutrient intake to maintain a livable body mass; a couple sets of plain tee shirts and jeans; and a minimal shared living space in a low cost of living area. That's quite below what the US considers the current poverty line and a quite bleak existence (and most people would wonder what's even the point of it).
Income beyond that would drive inflation, at least in the short term.
