ah ok cool gotcha. sure, you’re granted the permission to use the money at your discretion, and at that point sure it’s fine to call it “your money”. but the point is that not much hinges on that -

you’re not giving the state “your money” when they take taxes. they, alongside the rest of the distributional apparatuses, are the ones granting you money. it happens to be “yours” is the short-term possessive sense in between institutions, but that’s basically normatively irrelevant
