It's not about securing your device from external threats or bad actors; it's about securing the device from you.

I see it a little differently. I would change your statement to the following:

It's not about securing your device from external threats or bad actors; it's about securing the organization from any blame / wrongdoing.

Most organizations today are looking high and low to shove the blame to others instead of taking responsibility.
