I feel like it depends on the beach. Haven’t been to French one’s, but I’d bet there were some touristy ones that get slammed with people. Those make sense for this. Now, some of the quieter more locals only kinda beaches that people are able to spread out more, that’s probably fine to keep… but that’s going to be a hard distinction to make clear rules on.
On one hand, I absolutely abhor governmental blanket data collection and the storage of this data. Both from a personal privacy, independence and freedom point of view, and from a “you know they’ll just leak the data and then everyone will have it” standpoint.
On the flip side:
Any sane company or government would have already done this… not sharing data between agencies/silos is leads to inaccuracies, duplication of data and work (wasted time/money), additional complexity in data storage and gathering, plus it provides multiple attack surfaces for data breaches.
Also, I read that as “if one agency needs something they can ask the other one for it” which has likely been happening for centuries at this point and this is just another “Trump said we need to do what’s already happening so he can look smart and like he’s doing something besides golfing and accepting foreign bribes”.
