Because, it enables Guix to download and use pre-built binaries (substitutes). This is a feature many wound want to have as compiling a package can take a lot of time (especially when doing it for the first time). These binaries are built with their prefix directory set into '/gnu/store/...' and they will be valid only if they are installed into '/gnu/store/...' on your system. The `--prefix' option will still let you install Guix into a directory of your choice and still be able to download substitutes along as you didn't configure with a different `--with-store-dir'.
