This is an empirical claim, about what is possible in game design and game play, and I don't think it's true. It's not that hard to have a combat resolution system that gives the goblins a chance to cut you off, but equally gives you a chance to escape. Modern D&D stop-motion resolution is a very particular way of doing combat resolution, that is far from universal and that I don't think I had even come across before 3E was published.
That isn't what I said, though. This is what I said, "However, if we start trying to play combat like real life where everyone can react in real time to what creatures are doing near them, the game would bog down to the point where combat is simply unplayable."
That involves a lot more than just having a chance to escape. Goblin one moves, then 19 other goblins and the PCs have a chance to react to what is happening. Then all the goblins and the PC start reacting to each other. Perhaps the goblins all start to rush. But what if 3 pull out crossbows? Goblins will react by getting out of the way. The PC will react by trying to get to cover or low to the ground. The crossbow goblins maybe aim lower, or maybe move to get better position. And on and on. That just can't be effectively modeled and even if you try, it will take huge amounts of real time to play out a combat like that.
