The difference is you flipped the switch and decided to turn up to work without clothes. You decided to radically change your behavior and actions in the workplace. This will obviously have consequences due to your unsightly naked body offending co-workers.

When someone doesn't flip any switch, but continues to work exactly as they did before, they have not done anything you can label a "choice with harsh consequences".

Unvaccinated people are not suddenly shedding and dangerous, in the way a naked person is shedding pubic hairs everywhere.
