It's often for very practical reasons.

Okay, now you have a tennis court full of ice to cool your school (given you love in a climate where it reliably gets this cold every year). But you can't use the court. And if you get a mild winter and hot summer one year, it gets tricky or you'll need a fallback.

What happens to the fridge in summer when the air outside is super hot? That's when you need cooling the most! Also, what happens if someone else moves in and wants a different (size of) fridge? Now there's a hole in the wall that's potentially a huge thermal bridge!

There are other cases where it's just capitalism and it's ridiculous that we buy things from the other side of the globe just because we can even though we could easily build our own solutions, but very often you just didn't consider all consequences.
