MMT still has plenty to say about the private sector, as well as non-monetarily sovereign monetary systems, etc. It’s the common fiscal policy recommendations informed by MMT that mostly have to do with Government debt. It’s important to separate the theory from the policy - MMT is way more than just overt-money financing.

But yeah, the parent comment is confused, corporate debt (and private debt in general) is the real looming threat to worry about in a currency-issuing country that only issues bonds denominated in their own currency (such as the US) - not the Government deficit or debt.
