Yep, I read about the spacebar. I've also turned my mouse upside-down and propped it up against something to keep the button down. I've thought about auto hotkey, macros, etc. But the point is if we're all looking for alternatives outside of the game, then I think the process needs to be rethought. A stone, or a button latch, would maintain the same game mechanic without physically fatiguing our finger. Either that or the entire bench crafting system needs to be nerfed (which was another suggestion, and one I would be open to).
