As argued bazillions of times, the real point MMT is making is that the government’s budget constraint is the wrong constraint—the correct constraint is whether or not a particular budget position will raise inflation beyond an official target rate (say, 2%, which seems to be the choice of most central bankers).
Let me explain to Mr. Worstall and others how this could work rather easily—just as the CBO and OMB now evaluate government budget proposals regarding their effects on the budget stance, the CBO and OMB could instead shift focus on evaluating these proposals against the inflation target (I argued the same thing here, printable version here). Much like how policy makers supposedly take estimates of effects on the budget position rather seriously in making budget conditions, they could replace these with projections of inflationary effects. An inflation constraint provides more fiscal space than a budget constraint, but in no way does it provide unlimited fiscal space (again, as we’ve always argued).
We could add quite a bit of detail here if we want, but I’ll just say a few more things.
