It can still be useful. I don't agree with you that philosophy is not helpful (unless I am misreading you);

Philosophy has most helpful in establishing faith and belief in moral and ethical concepts by argument. Few societies would exist without them. However one should not forget none are proved, absolute, or fact. Some societies fail because of their philosophy and its inability to change. Their (concepts) strength is that most of a society believes the philosophy. Philosophy provides little or no new knowledge and resists change of any faith and belief that has appeared to work in the past.

" Philosophy has most helpful in establishing faith and belief in moral and ethical concepts by argument."

It has also been crucial in developing the rules of inquiry that we use in science, through the philosophy of epistemology. It's not just about faith and morality.

Not neccessarily. If applied correctly, it can expose false premises, sometimes to the dismay of the philosopher.
