In older games, "stacks" were simply represented as a quantity variable. Hence "dupe'ing" bugs, especially gold dupe bugs were prevalent in pretty much every MMO at some point. Newer games actually account for all the gold and items on the servers, at the cost of intended inventory space being reduced, and the glamour systems require the game to keep track of two items, not just one.
More to the point though, almost nobody has ever played a game where the inventory space was nearly unlimited and lived to tell about it. Everyone finds a way to work around the space limitations, even if it involves making it an extreme pain in the ass.
Because:
1) Every item requires being sent across the wire. FFXIV is so responsive because there are so few items being sent. Even not-so-old (freemium) games that let you buy expansion slots, were never this fast.
2) Searching inventory and market boards are fast (market boards occasionally time out), and searches check your Retainers.
This one time, in this one other MMORPG game, I lost my dress that I had worked so hard to get and dye the right colors... and lost it to a server crash because I had just changed gear. I will never forget that.
