Well you are free not to own it. Nobody's forcing you.
Actually my main mean of transportation in Toronto is bicycle myself (well I work from home for the last 20 years anyways).
I also own car (van actually) and it gives me great and hassle free degree of freedom. If I am in a mood and I often am I can jump in and in few hours be in complete wilderness swimming in some godforsaken lake. Or if I need to grab some heavy stuff and bring it somewhere which happens rather often. And I do not need to arrange / wait for anything. Just get in and go.
So no. Screw that dense car free living. To each their own.
