You're still going to end up playing with kids though. And they'll still be disruptive. So how do we go about improving the system for human life? By being better adults than the ones that I'm taking issue with. That's the point here. Matchmaking in Raids would fix the recovery time after losing a fireteam member. But if someone in your fireteam gets an error code and you want them back in, but matchmaking has already given you someone else... well, that's an issue. Then there's the issue of wanting to do a specific part of the raid so you can get specific rewards and loot, and you keep getting slotted into a bad place. Trying to get Warpriest and keep ending up at Oryx or sisters. So there's another issue.

Not if the game is going to ranked "Mature" and then have government laws forcing people to play games their age. Example: 13 year olds can play "Teen" rated games but cannot play "Mature" rated games until they are 17 years or older.
