I think you are saying what I am saying: in specialized cases EC is fine and a good cost saving measure. My only addition to that is that it’s popularity may be due to ease of developing EC databases vs ones with distributed consensus algorithms, and that personally I prefer to start with a system not based on EC, then add EC where necessary whereas it sounds like you prefer to start with EC and add constraints. I think your approach is more popular, but in my personal work experience it leads to more fragile systems which is why I advocate for at least understanding why that choice is being made. EC systems aren’t inherently buggy. They just by themselves don’t include guarantees that you might find useful or desirable for general workloads.
