Wait until you find out I use passwordless sudo. Surely you can't really believe that every Linux laptop is horribly compromised.
If you're going to insist on being one of those hardcore "I must be root" people then there's nothing I can say that will satisfy your urge. The same if you are one of those permanent Apple bashers.
However, for the benefit of more sensible people, I will point out:
1. I used the terminology "layered security" twice in my post above
2. By definition if you have a blind hatred of Apple SIP, you must also have a hatred of SELinux or AppArmor or dm-verity or kernel lockdown mode on Linux.
