No, those are benefits. Walls remove and/or restrict, befits add and/or expand. You're like, reversing definitions now to try to fit some strange train of thought.
And as stated earlier, FFXI/FFXIV are the only sub based MMO's without a cash shop. Both EVE and WoW have them, so expecting modern MMO's to release without them is kinda silly. Not to mention that as a F2P game,Tera relies on their cash shop to generate revenue...so it's kinda necessary.
