Maybe its just me, but when I play the Yor they don't have much in the way of economic structures for a long time. They are already limited on population; unless, all you do is build farming/morale structures. Everything else is really limited for a long time. The number one way the Yor has to build infastructure is farming. This is not on par with an economic stradegy of everyone else. If you don't have money coming in how do you manage stuff. The Ai already seems to not be able to handle this. Now you want to slow down their only source of income. if this is changed theirs not much they can do about that. Do you guys not really play the Yor, or do you guys like weak races. Really how good is an end game with only 4 planets. At least these 4 planets are going to rock right. This will seriously slow down production for a long time, or the production is going to be really slow. The Ai proves this is really hard to do.
My question is if you guys don't mind forcing Yor to trade to survive. Then why do you get mad when people have to trade to use their modules or the Thalans not being able to build starbases.
The Yor doesn't have good governments options. They lose economics on this. Their economics are already to limited. They don't have much in the line of economics building. All they can do is build limited farms with good morale. You can trade for other options, but relying on the computer for improvements is sometimes very slow. Not to mention the Yor is not fit that well for trading. They would probably have to give a lot to get economic techs. Don't say trade, Since you suggested slowing down population can you provide a solution for their economic problems.
