The requirement for bonds and taxes to prefund these accounts follows. MMT logic cannot follow coherently from that starting point. It could only flow from a counterfactual consolidated balance sheet operation where the Treasury had no such account.

I’m not sure if you are talking about the tax/loan account the Treasury has at the Fed or the self-imposed mandate that Congress “match” deficits with bond issues, but both are equally false. The Fed account is advisory in nature and only serves to define deficits, not “funding” anything. If the flow of currency is properly acknowledged it is quite obvious that neither taxation or borrowing can “fund” spending and that both are meant to draw down existing currency. The “first dollar” question quickly dispels the myth of “funding” by any other means than appropriations and simply “marking up” Treasury accounts by the Fed as directed by Congress, the monopoly authority Constitutionally allowed to create the currency.
