Why is it ridiculous to you that people want and need both shelter and access to a way of sustaining themselves? The comparison between a Porsche (essentially a status symbol that you buy so that people around you see that you have money - given traffic regulations it isn't really a way of making your daily commute shorter) and housing (which is a necessity) shows that you don't have a good grip on reality. And you don't want all bus drivers, garbage men, supermarket cashiers etc. to move to Texas and bring your garbage to the landfill by yourself.
