Do you feel that traditional cemeteries are a waste of space?

I do. I can understand that people would like to be able to go to A Place and sit and remember, but I’d rather see a big plot of land where people can bury ashes, and plant a tree or a flowering bush, or whatever they want, over the ashes. Install benches. Turn it into a big park.
Eventually it would recycle itself. I mean, face it. 100 years after you die nobody’s going to be visiting your grave site, unless you’re Elvis or JFK, so what’s the point of a forever monument?
