Goodhart's law is always in effect. It can't be solved because it's not a problem, it's a fact of nature with annoying implications. It's the echo of the observation that efficiency is fitness as its consequences ripple from the lowest levels of reality through systems made of people.

You can make an engine as effective as the laws of physics let you, but you can't solve the limits of thermodynamics. You can only do your best within them. Same with this, for maybe the same reason.
