My guess is that Apple wants companies to reinvent their programs to work well on a touchscreen, which has largely been happening. If you could just drop macos on the ipad, we wouldn't have things like Procreate. You'd just get told to install desktop photoshop and connect a mouse and keyboard.

This seems plausible to me as one of the reasons. Especially in the context of how windows devices favored mixing desktop and touch concepts.
