See? Not overkill. But the need for insulation and wiring does preclude the use of 2x4 stud walls.
As a side note - I have an uncle who tried to build a house using only metric back in the late 70s as a way of supporting Carter's push for the metric system. He gave up after 3 weeks.
96'' divided by 16" = 6 sections.
Insulation is available in appropriate depths/widths and slots in nicely between the studs.
Romex is threaded through various holes drilled through the studs to plug and switch points.
What's not to work?
