As a doomer, I think that's a bad analogy because I want it to happen if we succeed at aligned AGI. It's not doom behavior, it's just correct behavior.
Of course, I hope to be uploaded to the WIP dyson swarm around the sun at this point.
(Doomers are, broadly, singularitarians who went "wait, hold on actually.")
Of course destroying the planet to get iron from its core is not a popular agi-doomer analogy, as that sounds a bit too human-like behaviour.
