So I need stone to build a stone miner. But I don't have any stone, which was the reason to build a stone miner. Which I can't do because I have no stone...
Seriously though, the idea is quite neat. But you are missing a lot of quality of life improvements. Like shifting people from one place to another should be done in 1-2 clicks since you have to do it a lot. Checking what needs what to build should be easier. Tutorial is a must for such a game. Audio would be nice as well.
