Apple enforces those restrictions via the permanently locked bootloader. The main benefit of unlocking the bootloader on an iPhone would be to run a modified version of iOS that allows for the installation of unsigned apps. Apple wouldn't like it and might even get litigious over it, but still.

Apps intended for release onto alternative app stores in the EU, Japan, and Brazil still need to be approved and signed by Apple. These laws were nearly useless.

I'd run ios if I could build my own apps for it without begging for Apple's approval to use my own device.

Really, all I want from a phone is to be able to run Linux/xfce on it.
