I don't think it's a pointless restriction. It's like saying that a monster's stats in tabletop might as well be visible to all since you could just look it up.
Yes, people who want to get through every encounter as easily as possible will just look it up. People who have TROUBLE with an encounter will look it up. But I can tell you that I, personally, would not look it up right away.
...so don't look it up.
I fail do see the problem here.
If you think Examine gives you too much information, don't use Examine.
You control the buttons you press.
