The other thing OP forgets is there's no mail system in game currently. I have stuff in my bazaar for LS mates to trade since I can't SEND THEM ANYTHING! And honestly, your point about correctly using the bazaar falls mostly on def ears especially those of us who have been playing since launch or prior; there wasn't space then there isn't space now. To many useless or unneeded items, to many limits on the process for using those items. Example of this, materia. No one or HARDLY anyone uses the level I-II materia; you go through those levels too fast to make it worth while. If SE came up with a different use or the ability to multi-slot those lower tiered items that would clear up space. Make them worth GC seals or something!
Also, the point brought up earlier about standing in front of areas to sell your wares properly in your bazaar and the 40 PCs viewable onry ... you will miss most people as you run by them ... they won't have populated yet. Especially in front of busier areas.
