Great Wall - Useful?

[Sir Blah]

Hey all...

Question..the Info Center entry for City Walls states:

City walls only provide a defense bonus of 50%, and disappear once your city reaches size 7. Size 7-12 cities have an inherent defense bonus of 50%, and cities larger than 12 have an inherent bonus of 100%.

The entry for the Great Wall states:

Doubles effects of walls in cities that have them. Doubles attack strength vs. barbarians. Expires with Metallurgy

Am I to take this to mean that (besides strength vs. barbarians and cultural significance) that the Great Wall offers no benefit if all your cities are size 7 and up?

I usually rush to get Construction and get my aqueducts built, so am I wasting my time going after the Great Wall? Or does a size 7+ city have walls assumed to be built around it?

Like many of us, I like the Great Library, and would consdier that far before the great wall. If you are already whupping up that much that you can afford a city to build the great wall, go ahead for the culture value later in the game, but for its benefits I don't think they expand to include size 7 cities and above.
