When someone lives off of public benefit, there's a sense in which the public can have an interest in how the money is used -- its use should correlate with its intent.

That's why SNAP money is restricted to particular categories. So caring about how it's spent is already a foregone conclusion, and rightly so.

If someone wants to spend money however they like, they'll have to earn it themselves. Even inherited money carries a sense of obligation to honor the family with how it's used (like not blowing it all in a week of lavish partying in Vegas, as an extreme example).
