There are two sorts of claims floating around in this thread, both by people who support and oppose MMT:

1) MMT is just a more accurate analysis of what we already do.

2) MMT is a panacea that will allow us to implement social programs without worrying about the cost.

I might be able to buy 1), but for the reasons Dead Reckoning and a few other posters have noted, 1) doesn't imply 2) and seems inconsistent with it. If it's just a new way of analyzing something and doesn't involve substantive policy changes at all then whether or not we should prefer it is an entirely academic question.

I also don’t get how the theory is really that useful, except as a way to promote government spending if you don’t think about it too much. It seems to make similar kinds of predictions as the government budgeting type of thinking, except it involves a nebulous quantity (inflation risk).

Theory accuracy is not that useful if in order to take advantage of the theory’s improved accuracy, you need inputs to the theory which are not easy to estimate or obtain.

I think everyone understands the theory, the question is whether that theory tells us anything useful about how we should run our government. Because same people are saying, "well, it's really just a more accurate way to model what already happens"

Agreed. It isn’t a very useful “policy design model”, to use lingo from engineering, because one of the key inputs to the model, inflationary risk, is hard to predict.

I’m not sure how you meaningfully apply the model to make government decisions in real time, except if you don’t think about it too much, and just want to say:
