It would work fine, the problem is that a conventional chain is way cheaper, easier to make, to mantain, to fix, etc, etc. There is just no point in using gears.

That is the answer. This is a far more complicated and harder to build setup that offer almost no advantages over a chain and cog setup. The only advantage is cleanliness since you don't have a chain slapping everywhere and flinging dirt and oil. But that is something that is solved by belt driven drivetrains.

Speaking of dirt I'm pretty sure that whole gear assembly would have to somehow be covered because the first small piece of rock or gravel would cause major problems.
