No fud but is my observation a concern or just a bad hypothetical

Just before I ask my question, I’ve just been looking into makerdao and have been very interested in the economics of the system, so if My question seems bad I’m sorry. So I was wondering If dai becomes one of the most used eth projects, because it’ll be the new standard for stable coins after terras mess, then would the success of dai effect the price of eth? Could this be a bad thing if it’s true because if eth decreases in price because of a decrease in dai’s price/depeg, then could we see a ust and Luna like behaviour where the decrease in one’s price effects the other ? What prevents eths price being effected by dais behaviour if it’s one of the most used protocols on the eco system ?
