You have root access anyway, via the pi user which can sudo to root when needed. See

I agree with them regarding safety too

You can also run a superuser shell by using sudo su. When running commands as a superuser there is nothing to protect against mistakes that could damage the system. It is like disabling the safety guards on a machine. It makes it easier to access the insides, but the risk of damage is far greater. It is recommended that you only run commands as the superuser when required and to exit a superuser shell when it is no longer needed.
