In this model the nobles don’t recommend a further tax if in aggregate they have 50% of the total income, utility is logarithmic, and they care about themselves as much as everyone else put together.
(This is a good argument that this model may just not capture your intuition. But I do think the case for taxes is in fact quite a lot better when the nobles collectively control a large share of the income rather than just being individually wealthy.)
