Yes - you are only naturally short the housing you will need for the rest of your life, but if you own a house then that represents housing for the rest of the asset's life.
If the life of the asset is expected to be significantly longer than your life, then you are indeed slightly long in housing.
Similar reasoning applies to willing your house to your kids (or whoever else) -- that's potentially a lot of value you can transfer when you no longer have housing needs yourself.
If the life of the asset is expected to be significantly longer than your life, then you are indeed slightly long in housing.
