Because technically every big ship would have been destroyed trying to stop narada.

Also because if someone keeps a gen5 they could have a huge advantage over other smaller surviving navies. Plus, since it would take decades of RP time for the wrecks of ships destroyed in the apocalypse to be salvaged and put back into action, as well as for new big ships o be built(thousands of years means none of the shipyards will be in any shape to be used immediately after the return)it balances things out a bit. A short return to the days of old fighting.
