Yeah, and so what?
The underlying assumption behind this kind of move seems to be the belief that small local bookshops are inherently worth protecting. Why is that? It's not like if a bookshop closes the land it occupied is salted with radioactive waste. Something else, possibly something more useful will move in.
The real problem here is not Amazon or books or even Google, it's the French mindset that things should never change, that the old ways are always the best ways. Perhaps France has an unusually elderly set of politicians or voters, but you see this in all its areas, most notoriously agriculture. Old ways of farming were put on a quasi-religious pedestal and vast amounts of EU policy and budget were redirected towards preserving them.
Fetishing bookshops doesn't have any emotional appeal to me - they're just buildings stacked with a small and limited selection of reading materials, which inefficiently deploy land and people. Given the rise of the e-book even large chain bookshops will likely disappear over the coming decades, and who will cry for them?
Perhaps the space the bookshops used up can be replaced by coffee shops - spaces for social interaction and work, where reading an e-book and then meeting a friend and having a nice conversation at ordinary volume is a perfectly acceptable way to spend your time.
