I’m beginning to think you might be trolling but I’ll give you the benefit of the doubt.
Some estimates put literacy in the ancient world as high as 40% excluding people who could read and write their name and basic words The decline in literacy after the Roman Empire is well documented and didn’t increase again until the Middle Ages. Buring and Van Zanden put the year 1451 as the point when it began to rise again.
so, now, do you have any sources for your claim about literacy not being uncommon?

If you want to see some discussion have a look here https://forum.paradoxplaza.com/forum/threads/literacy-rates-of-the-ancient-and-medieval-world.340325/
this isn’t a source, it’s another discussion thread like this one (and even on that thread there is no consensus)
