It's faulty, since you're only allowed 9 gloves in one trade, which doesn't even total to a higher worth than the 2.1b cap.
However, you can extend yourself to 4b per trade instead of 2.1b when using both meso and gloves. Gloves are mostly used for nx -> meso conversion so you can buy white scrolls and use those instead. 10b per slot (assuming price is 100m each, but I know it's not) never looked so good until you try WS hoarding.
I've covered pylons you know. Frank West responding to Protoss after being asked to construct additional pylons.
