(Please don't make fun of this aspect. But uis tere a moral reason not to emlpoy it?)
Another way to be more area-economical plan might be to use some kind of above-ground structures with vertical shelves like in many cemeteries.
In this state, the veteran's cemetery already permits a vet and his/her wife to be buried at the same plot vertically.
I'm not being irreverent here, in pondering on this.
Could we give a Navy veteran the opportunity of being buried at sea, as one choice? (I know, this is kind of hare-brained.)
How about some other ways of permanent storage that allows the family and the public convenient access, eh?

My father was a WWII Merchant Mariner, he was laid to rest at sea with full military honors by the Navy when he died in 2005 due west of Key West and due south of New Orleans.
So I think that option already exists.
Even more of a tangient, there are places much more bizarre than this. in crowded Hong Kong, you can "rent" a crypt / cemetery plot for 7 years - someplace where family can gather for a funeral and memorialize you for a while. After that remains are dug up, and expected to be sent elsewhere. I've seen it - excavated bones are left on the crypt, out in the open, before they are taken away
