Another way to think of the fallacy of broken window fallacy

The boy threw a rock at the window and it was cracked. It was not serious. By chance, it broke the thermometer hung on the window. However, it does not appear broken. The shoemaker not noticing it does not heat the store enough because the thermometer shows it is warm but it is actually broken. There are solutions. The shoemaker, as soon as he finds the thermometer broken, he may buy another one. However, it costs and buying a new thermometer is unnecessary for his business. In addition, buying thermometer itself does not heat the store at all. Another way, which I prefer, is to simply heat the room warm enough to make him and his customers feel warm. Even though his thermometer says it is one million degrees Celsius, why would he have to be bothered? He only needs more heat in the store.
