I mean, an ideal voltage source also cannot exist, and I'm sure their existence would violate several laws of physics. For example what happens when you put two ideal voltage sources in parallel? or when you connect one to a short circuit? Despite that though we can use a combination of ideal elements to represent real, non ideal, physical devices. So in that sense I disagree with your statement that "in this framing, all of circuit theory is unphysical."
