It's not that nobody cares about physical security, it's that physical access opens up entire classes of attacks that aren't possible otherwise, like physical keyloggers and bridging airgaps.

If you follow defense in depth as a security architecture philosophy, which the industry does, then you still implement defenses against physical attacks, but you recognize that those defenses are either (1) defenses against opportunists, or (2) last ditch defenses.
