Supposedly, all the Paris 2024 new accommodation were designed with re-usability for the general public after the Olympics. Is it possible that had an impact the swimming pool on design choices ? Put differently, are performance design at odd with more general/accessible design in the case of a swimming pool ?

Given the pool was put on top of a rugby pitch, which resulted in the shallower depth because they didn't want to destroy the pitch (a full depth pool would have weighed too much) - unlikely. The pool isn't a permanent structure, it's not going to remain there after the olympics are done.

I would be very surprised if they re-use it at all - an "above ground" pool of that size seems like it would be more trouble than it's worth to maintain over the long run.

I can't speak to the French ecosystem, but in the US these pools often (usually?) get resold to swim clubs who find some land and build buildings around them.

Sometimes they just move the pool to a new city and set it up in an arena for another championship.

Given the abandonment of olympic venues all the way round the world, I don't think this is a bad thing.

There's a lot in the book Soccernomics about how the economic value promised by politicians lobbying for hosting things like this rarely pan out.

There's definitely economic value but it really only goes to the companies building facilities, the suppliers, and the hospitality industry immediately surrounding the events. In an already well-developed city, they aren't going to be building many new permanent structures. Many will be temporary that will eventually be torn down or just converted back to what they were originally. The money is spent, distributed to the companies that directly participated in the build up and run of the Olympics but there's little gain made after.

A more interesting way of doing the Olympics would be to only allow for developing countries to participate in the selection process. Each country would be required to meet a certain level of funding to guarantee they can support the entire Olympics. Foreign investment would be encouraged. There would be a requirement for some aspects to be permanent construction, you couldn't just build a tent city for the athlete village. Then a name is picked randomly. The host country then receives major foreign investment, not just in sporting arenas, but in many areas of its economy. The Olympic committee could also collect dues from participating countries based on GDP that would go to the host country for economic development. It would basically create a lottery system for the economy of developing countries. The build up to the Olympics would create the infrastructure needed for future investment. This would likely require host cities to be selected much further out in advance. An oversight committee would observe the development and if milestones are not met, a host city from a developed country that does have the infrastructure necessary would instead be chosen.

In this case, the pool is temporary. La Défense Arena is usually used for rugby (Racing 92) and concerts.
