I said the political will does not exist (in several different ways) now you say:

Something that you can't implement, doesn't work. In practice MMT is a smokescreen for politicians to print money for their friends.
The point is, you don't "implement" MMT. It's a useful framework for analysis regardless of what policies you choose. If we could get to the point of discussing monetary and fiscal operations from a sound basis, then we can start debating policies, but we're so far from that at the moment.
I'd argue a less correct framework that you could actually sell to voters and politicians would be more successful by the virtue of its policy actually being implemented (not just the fun bits).
I can find you far more people who wish to abolish the fed and return to the gold standard than people who are willing to have the levels of taxation required to limit the inflation caused by funding the government with unsound money.
MMT's advocates policies would work if it wasn't for that pesky democracy and realities around campaign finance.
