If you read my comment, I specifically add a caveat for hydro.
In terms of solar and wind, of course we cannot just build unlimited amounts, but we can ramp up capacity a lot more easily and quickly than with nuclear, because it’s a lot simpler and faster to build (especially solar). Imagine if we increase construction capacity by 10x tomorrow; we would still need to wait for 15 to 25 years to see any impact with nuclear, while solar and wind would go online next year.
Of course, ramping up production brings an increased risk of manufacturing faults and construction errors in all cases. But I would argue that any nuclear accident is a lot more undesirable than some solar or wind power going offline.
In terms of nuclear fuel, these alternative technologies may exist. But again, the time to market, and the fact that we are introducing a new technology into our vastly expanding production capacity just brings even more risk and uncertainty, which is completely unnecessary when extremely save and reliable, well tested alternatives exist (solar and wind).
So what I am arguing is that we focus our limited resources and money (the latter being the key factor in our economy, unfortunately) on the things that have the largest impact in the shortest amount of time, and that is solar and wind (and to an extent hydro).
And again, all that analysis is graciously disregarding the very real risks of nuclear power (instability, war, proliferation).
Except for funding, obviously.
And as I said, the main point is we need clean, renewable energy as soon as possible, which only solar and wind (and to some extent hydro) can provide.
