If you have stone, you can use walls (100% to production) to turbo chop a lot of city improvements/units or possibly other wonders which require marble (which you don't have). You just have to time the chop of all available forest squares to finish before the wall finishes and you get the 100% bonus to production carried over to the next improvements you build.
Combining this early game with a forge and organized relgion can give quite a boost, producing every turn something.
Finally you can use your wall for something useful, For the rest they are pretty useless imo
Anyway, it feels a bit cheesy. I just tried this and had a surplus of 783 / 75 when completing the wall... And it was not even the great wall...
The same would work if chopping barracks with Toku or other city improvements for which your leader has a 100% bonus. Though the walls are nice and cost only about a single 2/3 forest square.
