Plastic bottles killed the "consigne", and it seems like we have neither the infrastructure, nor the will, to bring it back.

I don't know which geopolitical crisis might put us on a different track. A massive shortage of corn sugar ? A popular hoax making parents believe that plastic bottles will turn their kids gay ?
Plus, ever try and return a bottle as a "trash collector" ? Stores will throw you out claiming the bottle was not purchased in the store. So I would say 90% of bottles thrown out end up in a land-fill or in the sea.
I am not sure what you mean by the store turning you away… there is a location where you turn the bottles and cans in to get paid, it is not connected to a store. It is run by the government.
