This nails it.

There may be multiple reasons, to each their own. As a city-dweller since I was kid, the biggest issue, and the one that has me contemplate rural(-er) living, is the constant noise.
The housing market being what it is, it's very hard to find well-insulated apartments.
In France, there have been new construction regulations for noise insulation, but most of the apartments in Paris were built before that. You can more or less easily get an apartment that doesn't face a major road (or any road at all). But you can never get an apartment with no neighbors (unless you're extremely rich, which isn't my, nor most people's case).
