The networth is skewed that way now but when the war started our fams were all about the same size. I do see your point, but I think the situation is different, and here's why...
Don't you have allies to help you fight back? If we as allies are planning to attack someone, I don't think we should have to go after a family that's as big as our combined size (incidentally we didn't plan to attack you together, it just so happened our families were both independently planning to do so). First, there is more synergy with a single fam than with 2 fams that combined equal the same networth, and second each family is allowed, and should have, an ally to help them out. It's a fair assumption that you guys should have allies to make it an even fight, and that a fam as big as us and 79 combined would have allies that are probably the same size, and would kick our asses if we tried to take them on.
If you take the same logic and apply it to our situation with 77, it still makes it seem like 77 is picking a much weaker opponent. So while I see what you're trying to say and it did make me think a little bit, I think the two situations are much different and I'm not caught being hypocritical
