Um, You do know that that foundry daily is easily and often exploited right?
It still can be done only once a day. Regardless if you complete it in 10 seconds or 3 hours you get the same amount of dilithium and fleetmarks, yes, but, given that you get it once every 20 hours, this is not a big issue. One plays foundries for fun anyways.
For many, reward is something you get, currecny or item, with an immediate or further use. And many will repeat the same boring thing over and over again to get that very little amount of currency. What about the reward of having fun, playing for playing's sake ?
