But there will always be a housing market because shelter is one of the three necessities of life.

I disagree.
Because where we are going, we are going to undo all the damage done by the banksters.

As you said, shelter is a necessity.
HOW DARE WE price these things out the reach of young adults, and then tell young adults to move out?

We will start to make sure that every person has a shelter.
We, as a community will make sure there is a place for a newly born person in our world and in our community.

Further, in the near future, there will be so many vacant houses that getting yourself a house will be as difficult as finding an empty one and moving in.

Sooooo, no housing market.
