Milton Friedman style with a short but clearly listed/specified set of rules and punishments in the event of those rules being broken to ensure I can keep it that way without having to intervene
I don't veto even in the case of some clearly unfair trades and one that was suspicious in that it was accepted a week before the guy who clearly lost the trade dropped out of the league.
Maybe I should be more hands on but I find that opens a new set of problems. I suppose there is a threshold of trade that would require a veto but even then I would consult the rest of the league first
IDK just in general (without getting political) I feel every team has its interests in mind and has no incentive to weaken their own teams (without long term payoff) and thus diminish the quality of the league, so I prefer just to focus on finding stable, knowledgeable, committed members with a healthy degree of competitiveness and pride.
The weakness of this model of management is that I have a hard time kicking out someone who clearly has no idea what he is doing and does stuff like give injured Saquon for Mixon and Ingram to a 1-11 team that had already done unbalanced trades to become a top 3 team, give DJ Moore and an early 2nd round pick for Julio despite being 3-7 and eliminated from playoff contention--only for the guy who initially had Barkley and Moore to reveal at the time of the draft that he didn't realize dynasty (and the rules I listed out!) meant you kept the same players
The guy doesn't even have a full roster because he doesn't know enough players and pushes to get the rosters trimmed every few weeks to redraft sizes. By the 3rd and 4th round he was drafting rookies by how fun their names sounded and refuses to trade in the offseason because he doesn't see the point (again it's dynasty!)
And I can't kick him out without looking like a hypocrite and jerk
So take what you will of that: besides the occasional unbalanced trade that can be attributed to different player evaluations, my laissez faire commissioning works great when people are informed and competitive. When you have even one member who is only one of those two it hurts, can be exploited by other owners and is hard to fix
