This take is simply not based in reality. Compare what it took to gain root access to a computer 20 years ago to a modern iPhone and tell me again that there is absolutely no point in caring about security.
Amusingly enough, being able (or not being able) to gain root access to my own devices is one of the main reasons I can't address or verify their security - especially as official support is dropped over time.
Modern phones and other appliances have (or are) computers to which it is nigh impossible to operate as root. You might say you have to pwn them even if you supposedly own them ;)
