After spending most of my career hacking on these systems, I feel like queues very quickly become a hammer and every entity quickly becomes a nail.

Just because you can keep two systems in complete sync doesn't mean you should. If you ever find yourself with more-or-less identical tables in two services you may have gone too far.

Eventually you find yourself backfilling downstream services due to minor domain or business logic changes and scaling is a problem again.
