Nice try. The biggest reason why pirates don't have green cells is it would practically give pirates the ability to use any (green celled) faction tech anywhere. Which wouldn't be fair to the faction and would be imbalanced in regard to the independent pirate ID's abilities.
Plus the tech nerf hardly stopped you from using every single unlawful gunboat in the game in Rheinland on the pirate ID anyways.
And they're hardly equal. You get a "free to engage anyone anywhere so long as a demand is made and not met" ID compared to the "You cannot engage anyone unless fired upon or previously hired"
