As anyone who speaks French can tell you, the official body's prescriptions often have no relationship to the will of the people regarding how they actually use the language.
There's quite something to the polysynthetic view where modern French has a verb system with extensive clitics, but such an analysis devoid of appropriate genuflection to Latin gives les grammairiens anciens fits.
I don't see how the situation would be different with English (especially given that French was not as international in the 1600s as English is today -- so that ship has long since sailed). Not to mention that English spelling reforms have been tried many times in the past and rarely caught on within a single country let alone worldwide[1].

Surely there is an happy middle ground.

They are exactly that, less democratic, as the language standard is dictated by a committee of academics/politicians, leading to it often diverging significantly from the spoken language. In the most extreme cases language ends up used for the political purposes - for instance in my home country once known as Yugoslavia, following the break out of the federal entities into the new independent countries, there was a big push for separating each dialect of more-or-less common language spoken on the most of the territory into declaratively separate languages in order to backup the whole new politics of separate national countries and to deepen the gap between the new countries. So now we have 4 languages that are in spoken version basically the same, but standard languages differ.
It's actually the other way around, the standard languages are very similar, but spoken language differs greatly, even between different areas of one country, to the extent of not being mutually intelligible.
More importantly, why would you want to do this? It just seems like a compulsive reaction to the purity of standardization. If inter-dialect communication is the goal, why not establish a standard accent as well?
Other languages are less dynamic so they are less responsive to introducing new words. Some of those and others controlled by official bodies which may or may not represent the population are less popularity driven. In those cases a guardian relationship exists where words are vetting by others. English is vetted by all.
Saying that English is a pretty anarchic language would probably be a more accurate statement, not that there's anything wrong with that fact.
