There may be something you want to make that cannot be made that way. This is because understanding (and knowledge) decay over time, so if what you want to achieve requires a large amount of understanding, you have to work quickly. Additionally, if you want to do something very creative, then you have to fight against distraction and mistake (which I believe is absolutely necessary for real creativity). Also, I've found that sometimes pushing yourself to a point of (mental) pain can actually be quite enlightening. It's admittedly rare (say, 1 in 10) but quite valuable for reasons of empathy but also understanding pain, which is a prerequisite for making a large class of really useful things.
