Why are new forms of housing important?

Recently I was asked, “Why is it important to have these new types of housing as an option in LA?”
Things are changing.  People young and old don’t want to drive as much, and want to work in the community in which they live.  We want to collaborate and do things together, rather than try to be involved in many places and wear ourselves out.   Cities need to allow us to be creative and make the solutions that work for us.  The previous models don’t work for the current problems that we have.  We won’t be able to reduce our use of resources, get engaged in our communities, and have social support if we all need to purchase our own million dollar homes.  These things are all goals of cities, and we can make them happen if we are allowed to drive the planning.
