I believe that the lobbiists considered France in isolation. France is a country of huge area and e.g. the repeaters are quite rare. I think the 2m band is even less used there than in other countries.
I think: If you (maybe even in a French city, but certainly in the country) run a scanner at 2m, you will hardly notice activity within the 2Mhz.
However, the 2m is used less and less in comparison to the last decades anyway.
I can open 4 repeaters from home and call cq and rarely get an answer.
If you are on a summit in the Black Forest, the chance for 4 contacts in the FM is low.
And of course, the distances in amateur radio are not considered at all. Amateur radio lives for the most part on DX. Network planners also think in local clusters.
We can only save our frequencies when we use them.
