> The only reasonable conclusion to draw is that the industry has existed. It was world class, but the institutional knowledge to bring it back to this quality does not exist and would need to be rebuilt for the new generation of reactors. And we are not even talking Generation 4 here.
The only reasonable conclusion from your logic is that it would have felt like an even worse idea to build nuclear reactors in the 1970's. Yet, using today's hindsight, it was a great idea.
Airbus would have been a terrible idea: no one had built commercial airliners before, and only the US had the know-how. Today, we know otherwise.
etc.

Well it made sense for France for multiple reasons even in 70s. France didn't trust / like Anglophone dominance in the world. They brutally kept their colonies, sometimes to the bitter end. The mistrust to US/UK hegemony and the strong sense of nationalism is the reason we have Ariane and Airbus programs. Henceforth, they also invested in their own nuclear program. To make small and cheaper nuclear weapons, you need plutonium which can only be created in reactors. Even with that knowledge they burned fossil fuels majorly before 70s.
France built majority of their nuclear reactors after 70s oil crisis. So it made sense to have independent resources for them. So they won't need to rely on other nations, some of which were their former colonies that hated them. They had two strong reasons to keep a nuclear base electricity generations.

If the competition was renewables and storage rather than plants running on imported oil during the oil crisis it would have been.
75% of all new capacity in TWh (I.e. adjusting for capacity factor.) globally are renewables and storage. There’s no need to swim against the river.

Consider opportunity costs. If all the public money that Europeans invested to nuclear (it started way before the 70s of course) was put into renewables/storage r&d, we would have had great renewables decades earlier, and by now would be swimming in it.

That's just plain false, Airbus started as a cooperation between a lot of european aerospace companies, which had different a lot of know-how in different fields. For example Sud Aviation (later Aérospatiale, now Airbus) was the French part of the Concorde, they also had the Caravelle.
