Question

why force is called a necessary evil​

Answer 1

Friction is called a necessary evil because it wears out the materials be it screws, ball bearing or soles of shoes. This wear and tear increases the maintenance cost of the things.

But, at the same time life would have been a trouble without friction, as the energy could not have been transferred. In the absence of friction, if the object started moving it would not have stopped and kept moving on.
