Ok, so? Mythic+ would still not be in the matchmaking, and the entire point of Mythic+ is that the difficulty increases based on how well you can do. The precious rewards and higher difficulties that are supposedly the sole, sovereign realm of "skilled" players still exists, and is safe from the unholy taint of casuals.
Now, if you were arguing against putting Mythic+ in the matchmaking system, I'd actually be inclined to agree with you. The risk of losing your own, valuable, keystone to some untested, unknown scrub, is too great. Blizzard is already having trouble with creating a fair solution to people leaving mythic+ groups part-way through. That would only be exacerbated by throwing matchmaking on top of it.
