If this whole efficiency argument means I'm going to make $1 more per month while some lousy traders make $100k more per month, then I'd say: to hell with "efficiency". Fairness and wealth equality are more important to me than $1.
Also considering that these traders will use their $100k in ways that my $1 will become worth even less. For example by buying all the housing in my neighborhood and thereby increasing my rent.
Without that efficiency it'd be like the old days before electronic trading where you're paying 100x larger fees to a crusty old brokerage any time you want to trade.
