That's 100% my weird late-night word choices. You can reuse it for whatever.

I agree with your sentiment, but the wording is careful. Scaffolding is inherently temporary. It only is erected in service of some further goal. I think what I wanted to get across is that Yud's philosophical world was never going to be a permanent addition to any field of science or maths, for lack of any scientific or formal content. It was always a farfetched alternative fueled by science-fiction stories and contingent on a technological path that never came to be.

Maybe an alternative metaphor is that Yud wanted to develop a new kind of solar panel by reinventing electrodynamics and started by putting his ladder against his siding and climbing up to his roof to call the aliens down to reveal their secrets. A decade later, the ladder sits fallen and moss-covered, but Yud is still up there, trapped by his ego, ranting to anybody who will listen and throwing rocks at the contractors installing solar panels on his neighbor's houses.
