If building a city wall cost me 1f for each tile... heck, even if it simply didn't raise base production of the tile, I would never, ever build them. If walls are added as worker improvements, they shouldn't hurt the city's production, or they'll be just another useless mechanism that we complain about later.
Madscientist: Your suggestion for walls would make barbarians basically a moot point after masonry, which would be extremely unrealistic. Cities with walls were raided and destroyed by barbarians for thousands of years after that. The suggestion that castles obsolete barbarians is okay, but by then it's irrelevant because all the land will be gone.
The real problem with walls is that the implementation of siege in Civ IV is unrealistic anyway. So it's hard to improve walls or make them more realistic without a complete overhaul of the system.
I don't see the walls as being terribly poorly done, except that siege weapons are too easy to get, and that walls can be utterly destroyed too quickly. It should be a major ordeal to siege and defeat a fortified city with a castle before gunpowder, and a pretty big deal after that until cannons. That can be done any number of ways, but to me making siege harder to build would be as good a solution (or better) than beefing up walls.
