Which is correct?

Question

The usefulness of learning is considered valuable.

OR

The learning usefulness is considered valuable.

Answer 1

#1 is better, but it's kind of useless.

Of course usefulness is valuable, or it would not be useful.

I can think of a context where #2 is syntactically correct, but it's kind of weird.

Answer 2

Why not just write, "Learning is valuable." ???
