No, not everyone has to use the auger, but one could always turn the game volume down to 0 and listen to a podcast or what have you. The main benefit of the auger for me anyway is without it I would have to mine every night - 5 stacks of stone? 4 stacks into 2 forges and the final stack as an ingredient for concrete mix, or I'll have to turn all of it into sand - and instead I can just mine for an entire night and have enough stone for a few days. But again, to each their own.
