No you don't. What you need is a system where combat is actually dangerous and has consequences therefore is something to be avoided.
Picture a game of D&D where the PCs don’t fight, but instead avoid every single encounter.
Now picture your players’ faces playing that game. Are they sad? Bored? Both? Yeah, it’s both.
In D&D (any edition) there are basically no long term consequences other than death. If you're on 1hp you are still just as physically competent as if you are on full hp - and you will always recover given sufficient time. Which means that unless you die (very unlikely) there is basically no risk. In games with death spirals or long term wounds you want to avoid combat because it's possible that you will always have lost a finger - and because you are a lot less competent even after winning a fight if you've taken a few wounds.
I wouldn’t disagree with these ideas. They do seem like viable ways of making combat more dangerous and therefore good ways of making players think twice about getting into fights.
I think that having rules that don’t just make combat risky but make other options more fun is also a good idea.
