Old man: Furthermore, the lishmah is inherent in the baking process, a la machine matzah
What does that mean? There is a shailah about machine matzoh whether or not it’s lishmah, and as yekke2 wrote, the opinion that holds it’s okay assumes that turning on the machine is the act of baking which requires lishmah.
I think you just tried to wipe out the whole din of lishmah.
