Steam Users can't get Boxed CE?

[Syrellaris]

Square Enix didn't make the choice of not allowing steam to sell a physical copy, that is on steam. And even then, nothing is stopping you from buying a physical, its still your choice. Steam is for pc, so isn't it completely possible that you get a pc version not through steam? Either way, you only have to get the physical edition once per account, so you only need one for account-wide benefits

Square has confirmed you cannot use any other edition when you bought the original on Steam, so he can only get the steam version.
