Again, people are making things too indirect and complicated.
The thing you are complaining about isn't age, it is inactive players who can't be removed.
So make it that they can be removed.
We can remove rulers, council members, marshals, diplomats. So make it that lords and dukes can be stripped of their titles if they aren't "doing their job".
Seems like problem solved to me.
I very much dislike this idea. I would much rather see more definitive options like I said before. Allow a ruler to tax his Dukes differently, so he can raise taxes to 50% for more inactive dukes.
