You could argue that the French position: that the service could upset the French capital’s “commercial equilibrium”" shows a common-sense appreciation of the advantages of living in a neighbourhood where the is a good mixture of local shops and an attempt to preserve the benefits of this system. I'm sure that living in such neighbourhoods has all kinds of quality-of-life benefits in terms of communal life, neighbourhood cohesion and mental wellbeing that a strictly profit-driven approach doesn't recognise.
