Apple isn't good enough at software design to make macOS work on touch screens. Plus, they don't want to compete with themselves. Why sell an iPad running macOS when they can sell you a Macbook and an iPad instead?

Because now, at this price, there’s not a situation where I’d buy an iPad Pro over this. Although it’s marketed as a “pro”, device, a keyboard plus professional apps minus a touch screen is more pro than the same device minus keyboard minus apps plus touch screen.
