It isn't economics 101, though. It might be Austrian economics 101, but that's been pretty squarely rejected for being too simplistic a model.
The reality is everyone agrees: if you increase the money supply beyond demand for money, inflation will result. However, the demand for money is extremely difficult to model and is incredibly unpredictable. There's demand for US dollars all over the world, from dollarized economies like Venezuela and El Salvador and Panama - to European and Asian bond buyers - to unusual dollar demand curves at home, such as the sudden fear that gripped the economy during COVID that caused everyone to stuff dollars into their mattresses.
The model is far more complex than you're making it out to be.
