There isn't much demand for using phone as computer. If you are at home or work, you can buy a desktop computers for cheap. If you are traveling, you need to find a monitor and keyboard. You could carry small monitor and wireless keyboard, but then you are carrying as much as laptop. People who need to work on the road get a laptop. People who need to send email get iPad and keyboard.
Good example of the economics is that Macbook Neo or iPad Air are cheaper than new iPhone.
iPhone should export display, but more for showing videos or presentations. My Pixel 10 has USB-C display and I haven't used it, but I have computers for all purposes.
Apple should spend more effort making the iPad usable for work. It would be good candidate for USB-C display, but with iPadOS.
