Last I heard, Australia was still a free country and you choose where you want to live and accept the advantages, disadvantages, costs, etc. when you make the decision.
You are assuming that those who live in the outer suburbs are forced to travel to the inner suburbs. This is again a personal choice. If you wish to work in the CBD and don't like the travel, why not live near and save yourself money and stress. My inner suburb is surrounded and divided by three major roads. Morning and night these roads are bumper to bumper with CBD workers travelling to and from work. Yet the suburbs they are travelling to and from are well served by fast ferries, and air-conditioned trains and buses. Why do they drive?
Outer suburbs nowadays frequently have better services than the inner areas. Large shopping centres, transport hubs, government services are all out in the 'burbs now. I don't like travelling to outer suburbs for parts and services because this is where industry has moved to. But I accept this because I like living where I do.
