It's like creating a back door to a bank. It makes no sense first of all and second of all the banks would close up if there was a back door.
Banks already have a back-door: court orders. Once the bank receives a court order to fork over all your bank accounts' history and safety deposit boxes, they'll walk out with everything on the court order's shopping list a few minutes later.
They cannot do that with strongly encrypted devices where only the device owner knows the password used to scramble other keys.
