Your premise is that a person needing money not to starve is worried if the government knows their money is going to food? Or rent? Or a student loan? Or a hospital bill? I'll take at face value that this person does exist. They should take the digital payment and use it for a single or two lump sum payments they don't care about being tracked, like rent. Is this really a Binary situation, where as soon as one or two not so private payments are trackable, now you can't use cash for the rest anymore? Maybe just don't use government stimulus for private things? I'll buy this, if you're making a slippery slope argument about cash being completely obsoleted.
