You misunderstand, driving small farms out of businness so they can be taken over by Gates and other big farming monopolies is the real goal not an unwanted side effect.
a casual American perspective here -- it is easy to mistake the cause when an effect is obvious. Yes, coordinated market regulation ends up increasing consolidation (with capital). Not everyone thinks this is a bad thing. No, it is not a plot by a few powerful individuals (easy to imagine, convenient emotional target). Rather there are "policy levers" and economic forces that operate at once, and interact in complicated ways.
