There are 2 main concerns I think "only renewables" solutions miss:
1. Impact on land usage. The sheer amount of land required to provide 3-4x global use is impractical and has major environmental consequences. It's not free to pave over large areas with solar panels or make huge swaths of air unsafe for birds.
2. Cost of storage is usually projected using current prices with some decline due to production efficiencies. However, producing grid-sized storage would put such pressure on the supply of critical metals that the subsequent price rise would put bitcoin's performance to shame.
Whereas, we know we can scale nuclear to meet global demand, at least as a major base load supply as part of a mixed-generation strategy.
