Why is it necessary to change vehicle oil regularly, and not just change the filter and add new oil as needed?

Someone told me jokingly that “the first law of organic chemistry is that if you mix 1 kg of cherry jam with 1 kg of shit, you get 2 kg of shit”.
The oil filter can only catch stuff like larger metal shavings, it passes contaminated / burnt oil through. At some moment it should be discarded completely.
