What?? Balls!
Most French wines (and wines from everywhere else) are made to be consumed young, not to age. Perhaps 5% of the wine production benefits from age, and less than that ever get the chance - most consumers, and certainly the French themselves are included in this, drink the wine soon after they buy it.
And much of the wine made in France wouldn't benefit from acidification, but so what?
And I am at a loss to know what you mean by " Instant turnover when all that tannin is added means instant $$ to the winery"
No, _most_ French wines (in terms of volume) are made by large companies or Co-ops, and are machine harvested. The artisanal operations are very much alive, but represent a small fraction of the total output of France.
Many countries have regulation about what is, and is not permissable in winemaking (compliance varies). France is certainly not unique there.
And as pointed out above, only a very small fraction of wine made in France(or anywhere else, for that matter) is worthy of ageing, and even less is aged before consuming.
I'm not sure where you get the 'lifelong investment' part either - Bordeaux, for example, from good vintages in the 80s, can be purchased for less than the current vintage. I always thought an investment meant it would be worth more..... (I know he 80's wines are worth more than they were on release, but with a few exceptions, not enough more to make it any sort of sensible investment strategy)
