Because SE stupid and likes to do things ass backwards/wrong way and make it harder to want to use/like the system. Just like with housing, some years down the line after everyone bitched at their loudest they may put a band aid fix on it -.-
As for limits....
We're paying for a game that seems to be always running on limited resources. Do they have plans to do something about it? Nope. Seems not.
This is SE in a nutshell now - Take the players money from subs and mogstation, put it somewhere else and not into XIV.
