You are so wrong : if 19th c. France was so in love with the monarchy, Chambord would have been king. If he wasn't, it's precisely because of his utter inability to cope with democratic expectations. It took only some years for the Republicans to won (you know, by a popular vote), the adhesion of the french people, despite the 1870 trauma. Do you think a country who elected a Republican majority in 1876 was really going to go along with a King unwilling to let parliament decide public policies ? Where were the monarchists defenders in 1830 and 1848 ? That you do not like parliamentary democracies is not very relevant, this "instable" regime managed to stay in place longer than the oh-so-strong monarchic regimes you seem to like.
If Chambord had come in 1871, do you think that they would've necessarily still voted the same up until 1876? Like I said, he's gonna have some growing pains - both on his side and that of the ministers.
