You might be successful the first time on a certain project but if it comes to the point where they change their KYC process and required a video or you holding the paper then you will be caught. Even changes like that of 2fa recovery in case of a lost phone require you holding a piece of paper so imagine if you submitted a fake ID before, good luck in editing to make that fake identity to hold up the paper. But some will always find a way to cheat definitely which is unfair to those who submit their true ID.
