I believe I can prove you wrong.
This isn’t chess. The huge difference is the sides are definitely not equal, chess of course has 64 squares, alternating colors, and exactly the same pieces on both sides. Therefore, no bid is necessary, but white has tempo and I believe has a slight advantage if I recall correctly, so sides are switched. Soccer is the same. They switch sides in football and basketball at halftime because there are slight differences.
Axis and Allies is massively different. Even playing 2 sides and keeping the same setup does not make the sides equal.
In Classic with base rules, the Allies probably win 75% of the time or something, it’s horribly “imbalanced”. So if equal players played 2 games, each would win with the allies the vast majority of the time.
A bid necessarily gets the game onto even footing. It is not a handicap at all, which is what your extra queens are. This is where the huge difference lies, in that you are not putting extra pieces on an even board.
Global is also uneven, as proven by hundreds and hundreds of games. We tracked for many years the win % of each side, and as the Axis kept staying above 50%, the bids need to increase. The bid is game by game, determined by each player. The bid will always stop when one player says nope, I can’t go that low. That means he is satisfied with the setup, and so is the other player, who probably would have gone a bit lower.
IT IS NOT A HANDICAP, I think that is the major piece you’re missing. It is essentially what both of the players agree is a fair setup. You are not giving more bid to the other player because you think he is weaker than you. I can go on if this is not enough for you to see what I’m saying
