I've seen disturbing stuff too... I can see the artistic value in the proper context... and 100% it's the context that matters. What's the message here?
When you go to an art show like the one you describe, you're prepared ahead of time for this stuff. You have some idea of what you're getting into. COUM Transmissions in the 70's comes to mind, shock was a part of the point of it all. Or if you're into death metal, a disturbing album cover is sort of par for the course. Its part of the overall artistic message.
To have this stuff mixed in with commercial fashion, or whatever you want to call that nonsense, is much stranger. And the kiddie bondage stuff... in a commercial space? It's just too far for something targeting mass awareness and consumption. We're not all open minded people with an artistic bent who want to contemplate these kinds of things. This is stuff that belongs in the fringes, and I don't see how any normalization of this stuff has a net upside to society at large.
If they tried to show this stuff to schoolkids I'd be in the long line of people asking what the heck the administration was thinking. Anyone who has had kids knows what I'm talking about.
Also, to be clear I'm talking about the Lotta Volkova pictures, not so much the BDSM bear stuff which is in poor taste but not nearly as outrageous. The relationship between Volkova and Balenciaga isn't clear, but that's what I found first when I went down this particular rabbit hole. Examples here [1]. The kid taped to a chair and the bedroom full of blood stand out as particularly disturbing, the message of child abuse is clear.
