Cost should always be a consideration, but when people conveniently ignore some costs and focus on others, it does a disservice to the goal of decarbonizing the grid and it isn't clear what they are really trying to accomplish.
The levelized cost for residential rooftop solar is about as high as nuclear, but that cost doesn't seem to matter to some advocates and they continue to support subsidizing it. The potential costs for renewables + storage is about the cost of nuclear, but that cost also doesn't matter to some advocates. (If grid storage was cheap, we would have built it decades ago.)

Some advocates recommend massively overbuilding solar or wind to deal with seasonal differences. This is obviously at least a cost multiplier but that doesn't seem to matter to some advocates.
Advocates also describe how we will rebuild the electrical grid to move vast amounts of solar or wind power across the USA. This will not be cheap, simple or easy to protect against terrorism. Even the relatively small proposed Tres Amigas super station hasn’t been completed yet. The potential costs here don't seem to matter to some advocates.
Advocates for renewables seem happy with relying on natural gas peaker plants where necessary to get around the costs of building grid storage, but methane is a very potent GHG in the short term. There are lots of methane losses in its capture and distribution. No one concerned about climate change seriously thinks that burning natural gas is a long term answer.
It is possible there will be some major advances in grid storage that will allow us to stop using natural gas to cover for the intermittent nature of wind and solar. In that case - great! But... what if that doesn't pan out? The dangers we are facing in the coming decades are immense. If you were forced to choose, would you prefer the world to suffer through catastrophic climate change rather than use nuclear power?
