I disagree on "the most critical" part. You can be superuser at all times. I understand the arguments why not; I am pointing out that this is possible. Despite people claiming aliens will arrive and nothing will work, everything works fine when the superuser account is used too.

Also, I disagree that every company needs to pay the man. Funding is important, yes, but a *nix system is not crippled without sudo. You can change the permission systems. The superuser can do so too. It is not black magic. The permission system is trivial. sudo is simply a feature of convenience, not a "if sudo does not exist, nothing works" - that just makes no sense.
