I can.

I have seen framing crews leave site when their compressor goes down.

Or maybe more prescient; machine operators going home on a cold day because they can’t get their loader started.

I understand what you’re trying yo day, but my family ran a construction company for generations (until my father retired) and they had contingencies for every adverse scenario to stay on schedule: Generators, battery-operated tools, hand-operated tools, heaters for pretty much anything you can think of for extreme cold, wind coverings, etc. I don’t remember them ever stopping work except for a trade union strike.

I’m pretty sure doctors don’t abandon their patients during a blackout either, or even a war for that matter.

Mature professions have procedures and backup procedures for pretty much every non-catastrophic situation.
