Yes. And I'm explaining for anyone thinking this picture represents some sort of reality of the enshittification of finished lumber that nominal is not finished and graded size and hasn't been since 1919.

The 2x4 (rough) has had a finished size of 1.5x3.5 for well over a century, there was a very brief time it was standardized at 1-5/8x 3-5/8 but that was a pain in the ass for carpenters and mills. You can still buy unplaned lumber that is the full 2x4 or 2x6 dimensions, but it's ungraded and not suitable for anything but fences. It will not pass a building inspection.

This picture isn't saying anything useful.
