How can suffering not be measured? Wouldn't you say that a pin prick is less suffering than 40 lashes with a whip? That's an objective observation, and you don't need a cosmic dictator to tell you so.

Objective morality isn't "given", it is recognized. If it were given it wouldn't be objective.

Eventually you have to weigh one instance of pain against another—that’s where the subjectivity is more obvious. Can’t be measured.

Objective means external. All moral systems other than divine command originate internal to humans.
