Most of that can also be said for bars, restaurants, living rooms, gyms etc. If you have a kitchen at home, you don't need a bar and a restaurant. Soft drinks? Useless unhealthy pollution. Alcohol, even worse. Why have two rooms (bedroom+living room) if you can't be in both at once? And you're wasting space with then, and energy to heat and cool them.

Looking at the causes of death in the developed world, I think food (fast, restaurant, processed and junk food + sugary drinks) kills way more people than cars, even when accounting for pollution, brake dust, etc.
