I suppose there is always going to be a percent of players who will enjoy collecting ships to use in this very limited way, just as there are people that collect cars and hide them away in private garages.
That's not the vast majority of the player base and in that type of system the thing has to work extremely well with sufficient gameplay.
The assets have to hold their value (even appreciate) which simply isn't going to be the case if the game is released.
So that aspect is screwed too.
