GRANTED: The texts we have leave us with a puzzle about why the women went to the tomb.
DP is asking us to believe the following. The women were carrying certain spices to nurse a desperately wounded but perhaps not-beyond-saving victim of crucifixion. The victim was laid in a tomb, not because he was dead, but because the tomb was convenient for other reasons (cool, safe from interruption, etc.).
Problems:
(1) Why would they have expected Jesus to be alive after three days of neglect? Remember, according to this hypothesis, it's agreed that Jesus was crucified. We have no records of anyone else surviving a full crucifixion. So if he did survive, he would have been in really bad shape. Recall also that he was flogged with a flagellum -- an instrument of cords with pieces of broken glass and nails attached. He was struck over 39 times. Each strike would have drawn blood, and by the end of the ordeal, he would have been just about hamburger. Indeed, most people condemned to crucifixion died BEFORE they were hung on their crosses. So, to believe this hypothesis, we have to believe that, after witnessing their beloved prophet abused this way, and having gotten him off the cross before he had died, Jesus' "friends" ferreted him away to some tomb and left him there without food, water, or provision for three days or so. Then, they went to the gravesite expecting to find him well enough to be further nursed toward health.
Jesus didn't need to be left alone in a tomb for a few days of rest. He needed constant care, food, water, and other attentions. DP is asking us to believe that Jesus was abandoned for three days -- after a crucifixion of all things -- and then his friends showed up later expecting to find him alive. I just can't imagine that level of stupidity. At least, not in women.
(2) If they expected to find him alive, and they DID find him alive, and if Jesus survived, how did the community come to see him as "resurrected"? That word simply doesn't fit the situation, even if you regard his survival as miraculous. In other words, this account doesn't explain how the early Christian community, with its belief about Jesus having died and rose again, even got started. It certainly doesn't explain the high Christology of the New Testament, which certainly regards Jesus as the Lord of life.
(3) If this is what happened, where did the appearance stories come from, and how did they become associated with the story of the empty tomb? If Jesus survived the crucifixion and was nursed back to health successfully, the post-resurrection stories are completely out of place. (I mean, they're weird anyway, but this just adds a whole new level of weirdness.) If Jesus had been nursed to health, why would people be filled with wonder when they (finally) recognized him? Why would they have worshipped him? Why would they have been surprised at seeing him?
These are insurmountable problems for this "interpretation". Serious historical theorizing (as opposed to armchair theorizing) cannot take it seriously for an instant. When it comes to the discovery of the empty tomb, we are at foundational, bedrock history. To seriously doubt it is to render the emergence of Christianity as entirely inexplicable. Not even the rantings of Paul would have inspired Christianity if Jesus had survived the crucifixion and lived to tell the tale. Nor would he have inspired anything if Jesus had survived the crucifixion but subsequently (in a few months, say) died. Such a man could never be confused with the Lord of Life!
This isn't a matter of "well, you have your interpretation and I have mine" as though the competing interpretations are equally plausible and you can take them or leave them as you please, almost at random. What DP is proposing is completely nonsensical. Rather than accounting for the evidence, it cheerfully shunts it aside. At least the proposal that the women found an empty tomb and were surprised by that fact accounts for the evidence we have about the origin of the early church without distorting any of it. That can't be said of DP's proposal.
