I think the RMT fishing bots are the biggest problem. Take away those and there probably wouldn't be enough crystals to support the non-RMT botters. Also, the non-RMT botters definitely are not getting rich. It takes serious amounts of gil to get a craft to 50 in most cases. (along the lines of 100M for GSM for example, or so a LS mate told me) And once you get to 50 there are not many profitable synths, because there are dozens and dozens of others with crafts leveled. Just my opinion for the most part, but I think people have serious misconceptions about the issues at hand.
