Yes, but it also costs time and energy to create a fridge in the first place. If you are just continuously buying new fridges every few months, you will be wasting a lot of energy, because you didn't fully utilize the energy put into creating the previous fridge. RoI is the rule in business. You need to get returns out of your investment. If you have to continuously pour more money into the hole to keep it "up to date", that delays your returns. Sometimes to the point of making the entire thing "unprofitable", which is a very bad place for a project to be.
