Mathematicians come up with a lot of "useless" theorems with apparently no real-world application, but we don't ask them "What's the point if you can't use if?".
Anyway, people ask questions like, "How can we make Socionics scientific?" or "How do we know that Socionics is valid or not?".
How do we even know that its very approach is the right one? If the premise is wrong, then the entire conclusion is going to be wrong. If you want to answer those questions, then I think answering the questions of epistemology is going to be unavoidable.
