That is, essentially, and chicken and egg argument. 

None of them are really intended for long mothball periods.  There might be design features that allow you to mothball a ship more easily (like an airlock on the axis of rotation, if you intend to spin the ship to ensure even distribution of solar heating).  Those sorts of design features are (arguably) likely to survive as long as the ship is in operation.  

But after the typical 40+ year operational life, any materials designed to make it easy to recover a ship from being mothballed will likely have to be replaced, before the ship is mothballed. :)

(I sometimes write long term storage instructions for military vehicles and components.  It's a long list.  Even when prepped for long term storage, most of that prep has to be revisited on a regular basis.)
