You're playing a silly game by trying to make me state there is some "ideal" way the world "should" work, since everyone here knows the world isn't designed for anything. I can just as well demand you tell me what the ideal rate of change in temperature is. Note that you can't dodge that with "whatever the rate of temperature change would be if we enacted no policies", because there's no particular reason to think that whatever that exact amount is isn't too high (or too low!). The point is that current levels of climate emissions are much costlier and deadlier than a world where (good) policies have been enacted to decrease the flow of carbon into the atmosphere. Just to throw it out there, though, I'd suggest a guaranteed change of 2F/century would be greeted with an instant acceptance and sigh of relief by everyone.
