It is more then just "Have french bakery". Culture is fitting because it is not just the bakery that makes the bread great. Farms, delivery, trade schools, customers all are required for french level of quality.
A comment I've heard that I suspect has at least some truth to it is that France has something of a monoculture around French food. That may well be overstating it. But I think it's fair to say that there is a highly optimized supply chain around delivering a specific cuisine and rather high consumer expectations around that cuisine.
