The SS design can’t mimic the necessary inverse RIAA eq because its design is " different " and that’s why comes with its dedicated phono stage, you can’s use it with any other phono stage. No, it’s a design for other kind of LP recordings but not for the ones that comes with the RIAA curve.
You’re correct that the Soundsmith strain gauge cartridges require the dedicated SS phono preamp, but you’re wrong about everything else. The output of the strain gauge cartridge naturally mimics the RIAA curve very, very closely, so it doesn't need a conventional phono preamp to apply the curve. I’ve heard the Soundsmith system and while it may not be to my taste, it can certainly produce incredibly good sound.
