You buy a car. You buy a brand new car. It’s expensive. Your friends call you an idiot, but who cares. You love cars. You love that new car smell.
But imagine if, when it came time to buy a new car, you weren’t allowed to sell your old one. That car you bought brand new a few years back? You can’t trade it in for a new model. Now take things a little further: imagine if, from the second you plunked your buttocks in the seat and gripped the steering wheel, only you could drive the car you just bought from the moment it left the showroom till the day it hit the scrap yard.
