I'm not sure he's saying you shouldn't save. You could leave a good amount of capital to your kids too without owning a house.
I know, I know, someone is going to say "well, what about upkeep and maintenance and killing rats and xyz?" The way I'm seeing this (which, by the by, is originating completely from a 3-beer-deep opinionated loudmouth) is that it's negligible compared to the fact that you are investing your money in something that is of material value.
