Not being able to have root on your own device is a downside of GrapheneOS, not a benefit.

Depends on where you stand. I could always build GrapheneOS myself and enable root again but I just don't have any need for it and prefer the stronger security guarantees disabling root comes with.

You absolutely can root GrapheneOS, just use the standard Magisk process. I think the only downside is that rooting disables secure boot.
