The essence of a title is nothing more than privileges plus fief and population, isn't it? It's merely a matter of how many households to allot.
Li Youu's approach is to break down the title, first granting you privileges or land, then bestowing other things afterward. This at least can delay the era where there's nothing left to bestow, as someone like Chen Xi, who is just about twenty years old, has already become the Marquis of the Township and entered the ranks of the Nine Ministers, is basically destined to have nothing left to receive.
The greatest worry for a nation is such a situation where there's nothing left to bestow, not because your merits aren't enough, but because they are too many, so much so that the emperor doesn't have enough to exchange for your contributions, which is essentially the root of turmoil.
