Even if we had a perfect library of useful proteins and their utilities, the composition of these protiens, and the emergent behaviour within "machines" made by them, would be complex enough to be handfuls of classes of new engineering altogethor.
I think its like saying "we know how to make bricks and iron and bolts now, shouldnt it be easy to make a full scale functioning replica of the greater tokyo metropolitan area?"
Even if you came up with a spec for a complex tissue or just a fluid that functions as a standalone chemical factory, you would need to fabricate it. However many specific protiens from your library, in specific ratios, mixed and maybe even... positioned.
In short protein folding is just the first fundamental step towards this print any biological design out of proteins world that I guessed you are alluding to.
