So let's say 8 players in a queue troll party start withdrawing or not clicking commence. If the system didn't penalize the entire party that would be 24 strikes total, 3 per party member, instead the way it works now those withdrawals are reduced to 3 right? Except there's also nothing stopping those people from simply queuing by themselves and making those 24 withdrawals happen anyway.

So really there's no reason to penalize legitimate parties for what shady people might or might not do because they'll find a way around it either way. You say the way it works now is to prevent a loophole, but the even bigger and more blatant loophole is simply to organize in FC or an LS and solo queue if someone really wanted to troll the queue.

If anything the way it currently works now exactly promotes troll parties or at least allow them to be able to exist, just like T5 skipping trolls back in the day. What's there to stop people from making PFs to intentionally lock out people for 30 min? Aside from reports for abuse and blacklisting there's nothing else really, and sure 30 min might not be as bad as getting skipped to T5, but the flawed system still allows it.
