I still dunno why people are so found of warranties

For the same reason people buy house, fully comp car, medical, unemployment, sickness, pet insurance.

We've never been burgled, or made a claim on house contents insurance, but we still pay it, as it might only need one claim in 10 years to make it worthwhile.

As for AUC cars, they don't have to have BMW service history, neither is it a problem with trade in.

Well I've never heard of a BMW being sold AUC without full BMW service history. And I wouldn't buy one from BMW without it.
Regarding trade-in, sure, they might accept your car trade in without BMW service history but you're probably going to get a lower price and the dealer will probably jsut put it through an auction, just as they do with high milers also.

Well I'm talking from first hand experience not 'what I've heard', BMW main dealers do sell cars that don't have full BMW service history, and they also take them in part exchange and then retail them rather than selling them at auction. Never had a problem with warranty claims either.
