California is a no-retreat state, a fact that I found surprising given how liberal the state is. This bill attempts to change that (plus more it seems), bringing the matter closer to the ideological stance of the state.

Your intuition is quite correct that closed-loop means open-loop repeatability is not critical, but controlability (non-stickness, smallest possible controlled movement) still matters. Motors are well behaved and continuous, so even with s

I agree. The wire itself is not where the precision is. It's the reciprocating mechanism done by the wire. Regarding price, my point still stands that wire is not cheap enough to motivate its use. Your link actually proves my point
