Really? What about phone theft? If someone sticks you up and knows all it takes is your finger to unlock the phone, I would think they would be more tempted to do so, as it takes more or less the same level of coercion as taking the phone. And it's easier than fumbling around with a password... therein is the double edged sword...
Why couldn’t they force you to reveal your password?
Demanding a password introduces more error and more room for evasion than a finger, which as I said is about the same as getting the phone in the first place. You are right that in some, maybe even most cases, it may not make a difference. But when time is of the essence, additional obstacles are often simply avoided.
You also might ask who is sticking you up. For example, I believe there is fourth amendment literature re government officials that have gotten away with using an arrested persons biometrics to unlock a phone, in a manner in which compelling the release of a password would be illegal. Put another way, I can simply grab your finger or put your phone in front of your face, whereas beating you until you surrender your password is a lot harder to accomplish without creating additional consequences.
Still depends on your threat model. Not everyone lives in a place where stick-ups and random arrests are so common place that you want to inconvenience yourself 99.999% of the happy flow.
