I feel like an important thing he forgot to mention though is that it lets you allow multiple users to have root privileges without having to share passwords or SSH keys
Indeed useful to not having to share passwords. I think sudo historically started as a way to let some users in a company for example manage printer server settings without having a root password. (And I believe it was Ubuntu in 2004 which promoted sudo and forced the default user after an installation to use sudo to perform root commands).

Why would they need to share ssh keys? Ssh will happily accept dozens of allowed keys.
Oh true yeah I always forget about that
