Nobody does that. The problem is that you - like many others - look at it from the opposite side than you actually should.
The simplest form of the timeout rule would be - and AFAIK it in fact was, originally - that who times out, loses, period. And then people realized that it's not actually fair to lose in case it's not even theoretically possible to lose in any way. That's why we ended up with what's in FIDE rules.
Your hypothetic rule based on "common sense" has one big flaw: there is no consensus about that "common sense" you would like to base your decision on. You are right that "nobody sane" would play like a moron and get checkmated from the position you presented. Hm... and how about this:
lichess.org/editor/7k/8/6KP/8/8/8/8/8_w_-_-_0_1?color=whiteEveryone understands that you just keep repeating Kg8 - Kh8 until white realizes it's hopeless or stalemates you, right? So should that also be a draw if black times out? And how about this?
lichess.org/editor/8/8/8/4k3/4P3/4K3/8/8_w_-_-_0_1?color=whiteEven here, you might say that black would have to be a complete moron to get checkmated - and I would have to agree. And we could go on and different people would have completely different notions what is clearly a draw and what can be lost without being a complete moron. Few days ago, I watched a review of a game between two strong players (IIRC ~2100 and ~1950 FIDE ELO) where in the endgame both Stockfish and the GM commentating the live stream immediately saw that it's clearly a draw - but both players were convinced that they are winning - and one of them actually won in the end.
That's why it's much better not to step on the thin ice of "common sense based rules" and have an exact rule instead.
