An empty head is not the same as an open mind. There is no idea to shoot down here.
You invoked BGA to criticize point-to-point.
Invoking BGA in this context is invalid unless you can explain how this art project process could ever handle BGA. Which you have yet to do.
You suggest that shooting down ideas isn't productive.
What an interesting argument to present, while not only "shooting down" an idea yourself, but shooting it down as unworkable after it has actually already worked for decades, generations, for jobs of the same complexity as this post.

I can easily explain how this art process could handle BGAs. As mentioned in the article, you could swap the indentation+hand-painted circuit traces with screen-printed traces on a flat surface.
Defending one idea isn’t shooting down another. Point to point wiring has its uses, for sure. But calling it an “idiotic ash tray of clay and paint” is shooting something down. But again, i think you’re conflating me with an earlier commenter.
