Not at all. Nobody has really put forth "too cheap to meter" as a rationale for nuclear for 50 years or more.
The issue is that nuclear is currently the only reliable base load generation technology that doesn't produce carbon (except perhaps hydro for reasonable definitions of "reliable"). The other top technologies either produce carbon (natural gas and coal) or are unreliable (solar and wind).
I actually don't believe nuclear is "the future" because I think renewables + battery storage will be more economical going forward and less politically dicey. But France is currently the envy of the world for their energy generation save for some countries with unique environments that allow for a lot of carbon-free generation (e.g. Norway with hydro and Iceland with geothermal).
Beyond that, leaving out storage costs, what are the technologies that can cover the world's storage? And in what quantities?
Because if I think of lithium, wouldn't it be an environmental disaster to extract and recycle all the materials involved?
In general, I don't understand why basically nuclear is to be replaced.
It's been true for 50 years, assuming it will be true for another decade or two is not wishful thinking.

Batteries for short term storage and pumped hydro for long term storage.

No.

It's inevitable that the cheapest solution will win. Not the best, but the cheapest.
Well it's one thing though to use the storage for a cell phones and some cars, another to keep all the industries and homes going on.
Do you have any data about what you claim?
For example in italy of hydro, nothing has been built for decades, everything that could be used has been used. If we want to go further, it's necessary to destroy valleys.
Your arguments do not go beyond whishful thinking... At least you need some data.
