I searched for this question but I didn't find a clear answer, some of them say one thing, other answers say another.

I finally completed all side quests (I think) and all bulletin board quests in Xion and I know I'll be locked out of Xion if I go to orbit elevator.

But my question is: can I still go to the Wasteland, Matrix 11, Altess Levoire and the Great Desert for example?

I still need to collect a few collectibles and fish from there.
