I find the proposed solution that they don't actually normalize reality but instead merely suppress the reality bender power source
For the record, I'm more or less trying to achieve what dankaar describes, rather than the above.
But I suspect that is rather beside your point. If I understand correctly, the idea of having SRAs suppress "anomalies" rather than "reality benders" just makes your concern a more general one, coming back to the Time-Turner problem of "if this exists, why isn't it always used?"
And if the concern is about the site as a creative writing endeavour, rather than about in-universe logistics, then no amount of in-universe explanifying or justification is going to resolve it.
Which is why I asked whether you thought it would be more acceptable as a Tale. If I follow the logic, the answer would be "no", because if the concern is not to do with canonicity, having this is a Tale (generally less canonical than the mainlist) is not a solution.
ETA: and again, if I'm reading it right, your questions above aren't intended to be answered with clever in-universe reasons, but they are intended to be rhetorical, to show the drawbacks of the approach. Unfortunately people like me always want to try to come up with an explanation that satisfies the in-universe objections, so I can tend to miss the broader point (again, if that is your purpose).
