There are two reasons for this. The first is that we've become an unreasonably safety-conscious society, driven, at least in the U.S., by the litigious nature of our society. If something can cause harm, however slight, it must be banned.
eli's dog may have disagreed (RIP) .
Now with my moderator's hat on:
Caution - Debating the merits or problems with a safety oriented society or the roles of litigation and government in such things is definitely political and off topic on this photography site.
So let's not go there, unless it has a specific to photography component.
Moderator's hat off.
My point was "chemistry set" was a well-known phrase, known by many people that knew nothing about chemicals and chemistry. That describes most photographers: there's no reason to know how or why D76 develops film - you just need to know that it does. So it's "chemistry" (not "chemicals") that gets the job done.

Chemistry in chemistry set is an appropriate use of the word. I have no problem with people using "chemistry" like they do in photography--there's little point in debating it--just know that it's not used anywhere else and people in the chemical industry get a chuckle out of how photographers use it.
