I'm kind of lost by your contruction. Is the something we drop the same as the object we "lift"? What does it mean to lift the object? Try removing the pronouns, and being more specific with your steps.

Is this a thought experiment you came up with on your own, or do you have a paper you're citing? If the latter, do you have a link?

That would be even worse. Let the strong gravitational force of the Earth go through a wormhole located on a small platform in deep space, and drop a rock near the wormhole (not through the wormhole).

Then move the wormhole (and the gravitational force) elsewhere, lift the rock off the platform, and bring the wormhole back.

Your thought experiment clearly implies energy is spent moving the wormhole. That would be the energy needed to spend to move your example rock.
