The Blues skipper called the sight of players running in and dancing around each other without landing a blow as 'embarrassing'.
Under the league's hardline stance, any player who throws a punch is immediately banished to the sin bin.
There's hardly been a cocked fist let alone a punch thrown in 12 months.
"There is a lot of carry-on at the moment. You can't throw punches (so) I don't know why blokes run in," Gallen said.
"You look like idiots, really. Blokes running in and grabbing each other … it's embarrassing for the game.
"They should let you punch each other, really."
Gallen's team-mate and fellow Bruise Brother Greg Bird is another advocate of a return to the free-for-all days.
He said: "I think it's embarrassing really. People run in 30m and push.
"I don't think it's a good look for the game. Take the refs out of play by letting players sort these things out for themselves.
"I'd much rather see people stand up for themselves."
Wednesday night's match in which NSW finally earned Origin redemption was punctuated by a string of unsavoury incidents and cheap shots from both teams.
But the game never fully erupted, with players mindful of leaving their team a man short should they throw a punch.
"It's Origin. We ripped into each other. The niggle is part of the game," Gallen said.
"Both sides give it to reach other. It was a brutal game."
