It really seems as though the Calamity Scavenger is intended as a replacement for any kind of update to the Armoire. I really don't get why this method was chosen, or why they feel the need to lock items that the system acknowledges the player should have access to behind an NPC who charges you for them if you wanted to free up some inventory space.

Yes 1000 gil per item is utterly trivial for any level 70, but it still strikes me as odd.
