Imagine a World where your appliances just work in some sockets and not in others. Where the tires of your car can just be bought from one supplier because it was limited by the car manufacturer. Your toaster just accepts some kind of bread. Your pencil can't be sharpned except with one specific equipament. Your mechanical pencil can use just one kind of pencil lead because it has some specific size.

And now imagine a step further, where all cars, mechanical pencils, toasters, wall sockets... everything is disposable because some small detail or component has just one supplier.

Imagine how much you'll spend to have things, and how much you'll have to throw away when any small thing of it gets broken.
