Here is roughly what some communists taught me about the outside world once upon a time 😂. Is this the same debt monetisation you are talking about?:

Imagine you have a piggy bank where you save money to buy toys. But one day, you want to buy a toy, and you don't have enough money. So, you write a note to your parents saying, "I promise to do extra chores if you lend me some money for my toy." Your parents agree, give you the money, and you buy your toy.

Now, let's say your parents have a magic machine that can create money. So instead of waiting for you to do chores to get real money, they just use the magic machine to make the money they gave you. This way, they don't have to wait for you to earn it, and you don't have to do the extra chores.

Debt monetization is a bit like this magic machine. The government needs money for things like schools, roads, and hospitals. Sometimes, they need more money than they have. So, they write an "IOU" note (like your promise to do chores), which is a bond, and sell it to get money. Normally, people or companies buy these bonds, and the government has to pay them back with interest later.

But when the government's central bank (kind of like the parents' magic money machine) buys these bonds, it's like creating money out of thin air to pay for them. This is called "debt monetization." It's a way for the government to get money without having to raise taxes or wait for more money from people's taxes, but it has to be done carefully to avoid problems, like prices going up too much (which would be like if suddenly all toys became super expensive because everyone had too much magic money).
