One can only imagine the cost for these materials.
That is correct, one can only imagine the cost for these materials because nobody is refining them in space yet. But if they aren't cheaper to make there than to send there, something is wrong.
Do you think the raw materials are found in orbit?
You have to send the raw materials to orbit - then process them in a hard vacuum, with entirely remotely operated equipment without any maintenance available. What is wrong, and it is very wrong, is to think that this is cheaper than simply processing them to final form in a plant here on Earth, then sending the finished material to orbit.
