That’s the problem. Anyone can pick them up, but they don’t because there’s no incentive, and the lords are quite content not having knights. Actually it’s better not having any because all they do is cut into your tax revenue until they get their own region. It’s not a coincidence that the most stable realms typically average around 1 – 1.5 nobles per region.
There's no incentive to have an income...? Knights who don't take estates have no income.
The problem is clearly not with the lords, either, because they are putting up a ton of estates that don't get filled, despite your claim that they have no incentive to do so.
More nobles already means more power. Why do we need a new feature to repeat what is already true?
