Na I dont think it will be that easy
Atm it is so easy because some functions are missing and you can exploit gold everywhere.
-Rebellions can also occur in your kingdom, when they come
-What happens if they include a "denying peace proposal" option of a enemy fraction/army/party, because they know/guess that they are stronger than you, or just because you have the wrong trait or bad relations.
-For sure you cant flee out of battles without a loss of men in the future
-Maybe they will fix the money exploit and adjust prices/taxes so that you will get a hard time to build up an army
