What to do when whole family is not consistent with dog rules?

you can't beat your head against the wall - they don't treat their dog like a dog - when you don't you always pay a price in behavior issues - nice try and I commend you - I trained a dog for my father by your rules - he took her and followed your in-laws rules and guess what the dog became Marley the 2nd and my time and effort was wasted - deal with your own dog you sound like a wonderful owner and trainer
