I did not so state.

I characterised a particular usage model of sudo as such.

As for the rest, if it's not apparent to you that letting a credential
for normal user login also suffice for root privilege weakens security
over escalation to root requiring a separate password, I would prefer to
abandon further discussion as fruitless, and I do regret that this
turned out to be the case.
