Ah, this is a great point. Yes, I agree. My point is nobody should collect basic income for anyone else. The prison system shall not collect it on behalf of prisoners. Creditors (even the IRS) shall not garnish it. No one collects it in behalf of detained/imprisoned/kidnapped people.
There shall be no back pay. If you could have gotten basic income but didn't accept it last year, you can't get that money this year. (You might still get this year's distribution.)
