Just think like this: every time you do sudo <command> it means that <command> can read everything on your box, including that secret directory you just did chmod 600 on.
I don't think you can avoid using it fully, but just think of the above every time you type sudo.
example:
# id -a
uid=0(root) gid=0(root) groups=0(root)
# ls -lrt /home/opti/.ssh
total 20
-rw------- 1 opti opti 399 Feb 5 13:37 id_ed25519
-rw-r--r-- 1 opti opti 94 Feb 5 13:37 id_ed25519.pub
-rw-rw-r-- 1 opti opti 49 Feb 5 13:39 config
-rw-r--r-- 1 opti opti 928 Feb 6 20:59 known_hosts
# cat /home/opti/.ssh/id_ed25519 | wc

"oh shit root just counted the characters in my private key"
but how? by using sudo
(sorry for dumb questions)
reply
sudo means: execute the following command as root. (it means "superuser do", because before sudo we only had su - "superuser", without the... do)
opti@server:~$ id -a
uid=1000(opti) gid=1000(opti) groups=1000(opti)
opti@server:~$ sudo id -a
uid=0(root) gid=0(root) groups=0(root)
I think this is a bit over my head
