You use fastboot to unlock the bootloader flash a recovery image then flash the main Rom. Its not too hard.

  You say that as if there aren't countless pitfalls that can stop the process, e.g. phone not rooted, installing the tools to do it can be complicated, differences across operating systems, USB permission issues with the android tooling, tooling just not working for whatever reason, phone not behaving the way its supposed to once you are in the bootloader, recovery image doesn't install, the ROM download is bad, etc etc etc These are not random examples - they ALL happened with the phone I am now typing on. Its also not something a business could be built on top of, which is the original topic of this thread. Users expect single click installs.

    Rooting and unlocking the bootloader are different. Root is having root on the OS. The Bootloader is what loads the various partitions. If your phone's bootloader is locked obviously flashing is a lot harder. The mobile phone market is massive. Even if you can capture a small subset of the users you can make money. Not everyone needs a one step install process.

      Problem is that on some phones, for instance my S4, if you don't root first, you can't install an alternative recovery ROM. Without an alternative recovery rom, you can't install a new OS that is not signed, so you can't install CM.
