That makes sense to me, but if we don't know where that point is, how can we say that France has reached it? I'm not trying to suggest France has or has not--I don't know the French economy well enough to have an opinion. I also wonder if "economic activity" alone is worth maximizing for--like certainly more economic activity is better than less, all else equal, but I think we also want to minimize inequality (maybe we want to maximize for median household income or something?).

I don't know, I wonder the same thing. And does that number change based on culture? And what parts? And how many new businesses are starting up in France and adding good jobs?

I know that the French economy isn't doing great. And it would likely slide further if government spending slows down, but I'm unsure of the extent of that impact. But I wonder how much of the problem is the sheer volume of paperwork and numerous taxes that consume hours to complete, monitor, and review when you get audited.

I think the government should optimize for a lot of things (well-being, good health, outdoor, fun, no pollution, etc etc), but ultimately, you need money to pay for those things, and to pay for guns to keep Russia (or someone like them) from invading and taking them.
