If a figurative or metaphorical explanation is presented as literal truth, I think that can be disastrous, on par with religious myths that people faithfully believe. But metaphor presented as such can be useful in understanding difficult concepts.
Also, I considered arguing that "gravity thread" is an anti-concept, until I realized what you were doing and that there was no real epistemological issue to fix. Even if there were, it is risky to begin by accusing someone of rationalism. I prefer addressing the cause of the conceptual error, which is the original misidentification of the existent in question.
