I'm sure with some effort, molten copper could be poured into molds, and blocks would be made by the thousands.

It's been done. However, they supposedly aren't the quality we're looking for, and that's why we use machining. It's a lot better in quality, but costs more. These guys NEED quality, because even a minor mistake will make it not work altogether, due to being on the edge of acceptable cooling, rather than leaving a large margin, like we try to.
