It's a bit of a paradox: burial rites are among the earliest and most fundamental elements of any society we know of; but long-term maintenance of burial sites has always been a challenge. That's probably because, after all the fanfare to honour the dead (which is mostly a way to minimize immediate social disruption), everyone eventually moves on.

When my dad died, the funeral mattered to me. But the grave does not. Of course to some it does, but it doesn't take long before everyone it mattered to are dead too. I think it's fine to keep graves for those who cares, but that shouldn't really obligate society to keep them around very long.
