Supermarket customers will bring their own reusable packages that they will clean.

That would be extremely unhygienic. The first moron, who didn't clean his container properly and then got poisoned would sue the supermarket and that would be the end of that.

Sure - I imagine certain things could be sold this way, like eggs, or dry goods, but that would be quite impractical and would slow down shopping significantly. It would also require shops to have way more staff on hand to do all the packing. And it would potentially be more wasteful, due to all the extra handling of the products causing more spillage.

Throwing out plastic and glass for it never to be recycled is the worst scenario anyway.

Well, no - there could be way worse "scenarios", like burning the stuff, for example, but that's neither here nor there, because no one sane would propose that at this point (although I'm sure there are people all over the world doing exactly that, right now). Properly managed land-fills are perhaps not the ideal long term solution, but it's not nearly the problem it's made out to be.

Recyclable material is transported, cleaned and stored as well.

Not sure what's your point. Yes - recycling involves all this, which is why it costs money, in most cases - more than producing new packaging does. Also - many recyclables, like paper for example, can only be reused as lower quality product and require many chemical processes (like bleaching), which produces chemical waste, polluting water. Not all the recycling is equally beneficial and some of it is outright harmful.

To continue with the paper example - fresh paper is made of wood. If we buy it - we create incentive for businesses to invest in tree-farms, which - just like forests - are a carbon sink and produce oxygen, for years, before being harvested.
If you buy recycled paper - there's less incentive to plant more trees.

On the other aluminium is very good for recycling, mainly because it can be indefinitely reused with virtually no loss in quality and also because we have a very finite amount of it available on Earth.
