A significant benefit of IaC is the work-savings it yields for recovery from a total-site-loss event, or the migration to multi-geo/multi-site. Sure, very few IaC environments are going to make that sort of thing seamless--bootstrapping new infra from nothing in a hurry is always going to turn up every skeleton in every closet and require a lot of manual work. But having even 80% IaC automation yields huge time savings in those rare-but-impactful "start from zero" cases. Having even just the easy/copy-paste parts of the infra encoded in automation can be the difference between hours and days for disaster recovery, or days and weeks for creating a new geo/staging/whatever environment.
