It's funny how these sort of questions are always being used to counter a safety net for the poor, but at the same time nobody does anything about rampant tax evasion and avoidance, which is much much more money.
It guarantees a certain level of means. Obviously. It's not intending to address people who live outside their means; there are other controls for that. It's to ensure that a person's means is sufficient to cover their basic needs.
A person who is responsible with $10 a month may not be a credit risk, but clearly can't cover their needs; a person spending $10k a month when their job pays them only $8k is clearly a credit risk, living outside their means, despite earning enough to cover far more than their basic needs. You're strawmanning.
