I suspect the comment you're referring to there was George throwing out an intentionally ridiculous scenario to illustrate the ridiculousness of the problem itself.
To recap that discussion: a short (NOT link-only) answer has proved useful, and also motivated the creation of a longer answer which may eliminate the need for the original. George is saying this isn't a decision for moderators to make, although it is technically feasible for the community to do so if sufficiently motivated - then noting the sort of effort that would be required to eliminate this minor irritant.
Considered in this light, the idea is patently ridiculous: the answer is useful, outside of extreme situations it is not in the way, it is clearly not worth 20 people's time to remove it.
