Physical security is a moving target and a spectrum. Basic mechanisms can protect my computer if I leave it unattended in front of common hackers for a few minutes to take a leak at a restaurant. Another level of security is necessary for people with more access or tooling. At some point, basically nothing I do will help given enough resources by pro's.

So, it's not so simple. Otherwise, all buildings containing valuable protected by locks and stuff would be compromise because enemies had potential of physical access. They aren't. That's telling you something.
