It is true that the Watchtower leadership and its followers have not really thought this thing through to its logical conclusion, but instead plod along on a whole series of assumptions.
1 The Watchtower teaches that death results in annihilation, that is, being reduced to nothing. A dead person is as much nothing as he/she was before he/she was born
2 God cannot resurrect nothing. Why? Because there is nothing to resurrect in the first place. This is not to say that He cannot create them, or even recreate them from nothing. But resurrect? Nope. If God could resurrect out of nothing then He could square a circle, or create a stone so heavy that He couldn't lift it.
Can God resurrect Luke Skywalker, or the Lone Ranger? Nope. Why? Because neither actually exist. They are nothing. Can He create them if he wished? Yes. But that is not resurrection.
3 So what the Watchtower teaches, and what the rank and file believe, is recreation which by some curious alchemy that defies logic, they regard as resurrection. As you mentioned above, a recreation is a copy of the original, but not the original. My advice to all Watchtower followers is to enjoy this life, because this is all you get. Once you die, only a non-biological, empty series of memories of you remain, to be implanted into a copy of you that has no conscious link to you, except by implication.
4 In order for the person to be resurrected, there has to be a clear biological and organic link to to the original. You can call this enduring link a "soul" a "spirit" an "id" "ego" whatever, but that link must survive physical death to make resurrection meaningful.
5 The most demonic aspect of this recreation teaching is what they have done to Jesus. According to the Watchtower, when Jesus died for "parts of three days" he too, was reduced to nothingness. Thus, "parts of three days" later, since there was nothing of Jesus to resurrect, the god of the Watchtower, recreated a copy of Jesus, call this copy Jesus mark2, and simply poured the inanimate remaining memories of the original Jesus into the copy. So the jerk who is prancing about in the heavenly realms at the moment, enjoying the benefits of immortal life, did nothing to earn his immortality. The Original, who did earn this has vanished into nothing.
Sad.
