The Security Clearance is based on the individual but it is stagnant by itself. It becomes active with a new job requiring it and the new company controls/monitors the individual. It is turned on and off as required. On the high level, it should be turned off since the individual is no longer employed by the US Gov. If it is left active as a courtesy by the government, then all sorts of shenanigans can happen. I can see where deep state operatives provide them secret documents and since it is not illegal to do so, then there is no penalty to the illegal info provider thus giving them cover. TAKE IT AWAY.
