67 years old male with bladder stone measuring 2.8 cm or 28 mm. what are the consequences if does not get a cystolithotripsy done and live with it ?

Here are some ...: If he has not had much problem in urination or recurrent UTI, is able to empty bladder reasonable well, and has no suspicion of bladder tumor on imaging studies (CT or US), it's reasonable to just watch if he and his family understand the facts and are willing to wait. If not or in concern, remove it and perform other procedures to help bladder emptying as needed after checking residual urine, etc
