The usual reason people prefer burial over cremation isn't so much the sanctity of the body, as that there is a permanent space to visit, lay flowers, etc.

I've always been fond of the idea of funeral-home "rememberance rooms", where urns of ashes are stored in small "shrine" spaces that can be visited instead. Japan's pet cemeteries[1] in particular take this to its natural conclusion: grids of cubby-hole shrines creating the mortuary equivalent of a rental-box consignment store[2].
