You make a really good point and it would be relevant to this situation if it wasn't for the fact that some developed countries have implemented this policy.
The bigger question you should be asking is why haven't all developed countries adopted such obviously sensible policies. I have a sneaking suspicion that the reason is regulatory capture.
It's easy to scream regulatory capture but one man's regulatory capture is another man's sensible public health legislation preventing the re-use of food/beverage containers without being properly cleaned in a way that just so happens to almost always be be cost prohibitive. A lot of these "regulatory capture" things do have benefits other than enriching corporations but the devil is in the details so it's hard to pick out regulatory capture from special interests getting something they care about done. Except in the most egregious cases it's hard to tell which is which without being an expert in the relevant fields on any given issue.
So in other words you can't really say anything substantial about the merits of reusing bottles?
If that's the case why not take the time to look into the regions in the developed world that have implemented these systems and see how they work?
Someone else in the thread mentioned that the province of Ontario (which IIRC is the largest purchaser of alcohol in the world) has switched over to a system homogeneous bottles that are washed and reused.
If a region as vast as Ontario with a population of approximately 14 million can do this, why isn't it feasible else where?
