But ‘value is fragile’ teaches us that it can’t be a 1-dimensional number like the reals.
This is not in fact what “value is fragile” teaches us, and it is false. Without intending offense, I recommend you read about utility a bit more before presenting any arguments about it here, as it is in fact a 1-dimensional value.
What you might reasonably conclude, though, is that utility is a poor way to model human values, which, most of the time, it is. Still, that does not invalidate the results of properly-formed thought experiments.
