Well what's wrong about having too much of money? I mean I'd understand if you'll complain if you havent enought, but ...

First of all, in the early time you are on (50 turn) you won't have really good units, so stacks you have propably aren't really so good or high unkeep.
Second, if you are wise ruler and handle your kingdom well it's no doubt you have money. You know what I mean, you conquer what you should, you trade where it's best and your buisness is handled by best people you can get, not some random guys with -100% to trade income.
Just use this money. Spend it to *fix* f2cked up diplomacy system in this game and make good relations with other factions. Spend it on buing of some settlements without war maybe. Spend it for fun bribing random guys on the campaing map

) Be creative about this
