I think the sentiment is more "I want my players' party to be able to survive a large variety of monsters". Note survive, not necessarily win. As opposed to your hero getting automatically one-shotted by any monster X levels higher than you.I’m trying to understand the scenario where PCs would be expected to fight and win against much higher level enemies.
In other words, I think the sentiment is reasonable as long as it isn't narrowed in.
