Macron's fundamental problem on China/Taiwan is not that he is wrong, he is not, it's that there is no point in being right about such things unless you can impose your views on your allies or can afford not to follow them if the shit hit the fan, which France can't.

The problem is not even just our allies, but also people in the French foreign policy establishment, which used to be full of midwits reciting dumb Gaullist memes and now is increasingly full of midwits who just recite dumb Atlanticist memes.

Realistically, you can't have a foreign policy that is opposed not only by your allies, but also by most of the experts both within and without government, the media, etc. And the truth is that increasingly all these people are brainwashed with liberal imperialism even in France.
