Safety
Whopity
Are you also going to suggest that it's not safe to have a wheelchair user as a passenger in a commercial aircraft or as an audience member in a theatre because they would need assistance with evacuation in the event of an emergency and would therefore slow things down?
The information you refer to is only an issue because it is normally only made available in written form. If it is made available in other formats then it is possible for it to be comprehensible and an equivalent level of safety established.
That said, you are echoing my concerns ........
