I know. Nuclear provides base load power, which can be argued is not needed any more.

It can be argued but only poorly.
Feel free to offer corrections.
The argument is one of efficiency and load distribution. Base load power plants are capable of greater efficiency than variable ones. This is down to optimisations made around specific output levels and the infrastructure required to support said loads. For example if you know the characteristics of your power output and that of the grid you can build a transformer or switch mode power supply to bridge that specific gap. This outperforms variable input transformers in every case.
There is an argument that low efficiency doesn't matter if the source is renewable, but this fails to take into consideration the embodied energy cost of producing renewable generators, not to mention the increased cost. An inefficient system may not produce enough energy over the course of its lifetime compared to the energy it cost to make.
Finally, most sources of renewables are intermittent and are not necessarily related to the population's power consumption. This makes the storing of energy necessary in order to regulate supply. Storage of energy is a large source of inefficiency and one of the key areas that is being focused on. Base load plant is absolutely necessary to minimise this inefficiency as much as possible.
For a good overview I recommend this site from Penn State Uni: https://www.e-education.psu.edu/eme807/node/667
These sound more like arguments in support of a distributed power grid rather than arguments for nuclear.
You keep referring to inefficiency but in real terms nuclear is so expensive that inefficiencies in renewables are a drop in the bucket in comparison.
