From a layman's perspective, even I see they are shooting down the straw man. https://twitter.com/EconObservatory/status/1285948679610933254

No. the central idea is that the central bank directly funds all expenditure right now. Which is documented online by the BoE who say that all expenditure payments are made from the Consolidated Fund, at the Bank of England.

MMT says that all money issuance, be it through government spending , or through private loans, carry an equal risk of inflation. Considering 93% of money out there is created by banks, why say that it's the 7% of central bank money that causes inflation?

MMT also says that inflation, that is the increase in price level, is a function of the increase in prices paid by government when it spends.

Its not the actual total amount of money created, which this article suggests.

Venezuela Wiemer Zimbabwe!

Tell me what is the difference between money sitting as BoE reserves collecting 0.25% interest, and money sitting in gilts collecting 0.25% interest?

Every hyperinflation event resulted from the government choosing to increase the prices it paid per unit item, to keep up with the market. This creates a inflationary spiral upwards.
