I don't think it's an opposing position. I agree with Laurence that the relationship between physical size, nominal size, and applied size in our digital environments is basically uncertain. I'm saying that type design can't address uncertainty, so if you want optically tuned design for different sizes of type, you need to start from a an absolute physical unit, even if where you go from there in implementation of type sizing is relative and flexible. Then it becomes a job for text display to figure out the best conversion from the size of text actually displayed, in the circumstances in which it is displayed*, to the physical scale of the design axis to select an appropriate optically sized instance.

* Which might be e.g. on an electronic sign where the nominal size of type is huge, but is viewed from a long distance.
