Keep in mind that decommission doesn't mean that the ship is taken out of Starfleet completely, nor does it mean that the ship will never be used again in Starfleet. It simply means that the ship is taken out of active status. Unless she was slated to head for the breaker's yard, the Enterprise would likely have been put in the mothball fleet. The ship could then be reactivated at a later date as needed. After major wars, it's typical for ships to be decommissioned. Many are scrapped, but many are also kept in mothballs and reactivated later. In some cases ships are reactivated as much as 30 years after decommissioning.
