Extended sovereignty responsibilities are not for the impoverished, they must find ways of freedom from poverty, which is a benevolence question for other sovereigns. They are not for the ill or addicted, who are in the same category.

The sovereign earning money has a responsibility in this country to research the nature of income and to declare, when there is testimony of income, whether the testimony is accurate or not. If you're earning money but not federal-nexus income, they can't come for you; they can only pretend you're earning federal-nexus income and hope you deign to consent, or if you're especially annoying to them they can use illegal force, which is another separable question.

Frenchmen in Paris earn money, but it's not federal-nexus income for the US; they must follow their own laws. Since some money earned is not federal-nexus income, we have a responsibility in following our own laws to determine what money is and isn't. It's never been in the government's financial interest to help us sovereigns make this determination.
