Why is friction called a necessary nuisance?

Have we ever thought, about what would happen if there was no friction? Once someone pushed from the back of the bike, the bike would not stop. It would go on. No more fuel was consumed. We used no energy to walk. Since there is no friction, the vehicle does not make any noise. There was no noise pollution. As a result of friction, the elevator rope would not be damaged or torn. What benefits! right?

But if you think a little deeper, you will understand how much complexity would have been created if there was no friction. If there was no friction, the bike would have continued in one stroke. But that bike could not be stopped. Because as I said earlier, there is no friction. That means no brake friction. If there was no friction, the bike would not be able to stay on the road. Its wheel would slide wherever it wanted. If there was no friction, we would not use energy to walk. But we could not stand still. It is not possible to walk on a rainy day if there are no grooves on the bottom of the shoes. Then, if there was no friction, there would be no fear of breaking the elevator rope. But if there is no friction, who will stop the elevator?

With so many everyday examples, we may think that friction is a nuisance for us. But if we think deeply about each of those examples, we will understand that without friction, those events cannot happen. So even though friction is a nuisance to us, it is necessary for us. And that is why friction is said to be a necessary nuisance.
