It hasn't always existed, but it certainly exists now. People value assets, and will continue to do so. Any worldview that you (and others) might have will need to respect this view even if you disagree with the basic premise.
In fact, most people end up building some asset or other for their old age because it makes sense. The socialist ideal of housing for all is an anachronism, and the left needs to recognise that. Property ownership, like markets, is ingrained in the people, and as I have stated on the copyright thread you have to accept this rather than hoping that magically everyone will see the error of their ways.
Maybe in the future it will evolve again, if we are able to cooperatise the economy, or through some other method, but for now these are basics which are accepted worldwide. People own stuff for themselves, and their family. Any solution has to incorporate this.
