This is a good point, and it’s likely that for many people there will be quite a wide range in the variance of how they experience a disability. If so, then you’d expect most people with a given disability to disagree with the GBD weight, simply because they would personally rate it somewhat higher or lower than the average value.
EDIT to add: In fact it seems the 2010 GBD weights were obtained by surveying members of the public, so it could be the case that the weights are either higher or lower than most individuals with a given disability would have indicated if they had been asked.
