Cars are not a necessity these days, as proven by so many people that don't own a car and survive quite nicely.

This might be true where you live, and in most well-populated areas. But when you live out in the country,it becomes more difficult, and it's damned near imposible in my case since I live on top of a 1000' foot mountain (hey, it's a mountain for us jersey folks!) and the town is in the valley. And that's a little more than I want to go through after a long days work or for a gallon of milk.
I, as well as others I'm sure, would love to go car-free. But it's not always practical.
