When you make or use fake money, you are in big trouble because you are breaking laws and you'll be arrested and harshly punished as a criminal.
But when The Federal Reserve/Central Bank aka government does it, it's different. They are above the law. They are not not breaking the law but instead are saving the economy. No crime. Big hero.
If an asset's price is pushed up because people use large amount of phony money to purchase it, what do you think will happen? Well, nothing will happen until something happens. When it happens, it happens big.
