Cemetary plots are priced so as to provide 'perpetual maintainance', so the
owners get a good enough return on the original plot purchase to make a
profit and mow the lawns 'forever' Sooner or later the cemetary will be
recycled into a housing development and the former occupants moved into a
mass grave somewhere. I believe we will see a trend towards the cremation
of uprooted bodies in the future, to avoid the reburial. Possibly even
legislation forcing cremation if land use pressures run high enough.
At least cryonic suspension can reuse the storage space once the suspendee
is revived, assuming there are still conditions that technology cannot
remedy in the future. Density of cryonic suspension should be much higher
than a mauoleum, etc.
If cryonics goes to mass storage, I hope sufficient thought is lent to
keeping the remains identified such that the revived person can be given
the proper identity on reawakening. Visions of massive bureaucratic
screwups arise..
