Courthouses are handy but unless your going for spying or confusism Currency is beter, that extra trade route adds at least one gold per city, and maintainence costs are usually 2-3 gold at that point, the free trade route is as good so you can build more military or markets, which are beter than courthouses.
I understand how Org works, I just dont find it a very usefull trait, your right it adds up a lot late game, but the time you need every ounce of power you can get is early game, and I find its a trait that just doesent help with that. Same reason I dont play protective often, its a powerfull trait, but it really doesent shine for me till post gunpowder. I guess Org COULD be a good trait, but Fin will make you much more right from the get go, Char will let you support a bigger pop early on, Phi usually starts to help fairly early, Spi saves vital early turns, Cre helps define boarders. Org/Fin just doesent seem like a powerhouse.
I'm going to disagree about organized here. Firstly, having a built in courthouse effect is strong. It means much more rapid expansion, without the loss of scientific output. Adding a courthouse to that, is VERY powerful. It mostly shows when you expand quickly and have a decent sized army. I play mostly on noble, but I'm betting the effects are more apparent on harder difficulty levels.
