You are wrong. OP ships are the same as general use one.
Why?
They will accumulate among the players with time. And won't go anywhere.
Moneythinks are not going to work as intended while permanent.
Did you know that iRL every aircraft has a resource time and you can not use that aircraft when the time reaches the end. Even if you buy it and put into hangar and won't ever fly (Not speaking about that you have to maintain aircraft every week when it is on preservation).
