Technically there are situations where you can.
But never mind that, stalemates do need auto resolution. The timeout exists because you can’t rely on finding every possible situation, and you can imagine a situation in which progress is possible but no one wants to do it.
So with Poss v MM the MM will die sooner or later, but stalemate resolution still makes sense because it could possibly take an absurdly long time.
CL v Prince needs a stalemate resolution because they literally can’t end the game without leaving even if they coordinated
Ect ect.
