There'll be no technology solution for this that scales globally for any means and usability

How about glass bottles and reusing them like we used to.

Probably higher skill and cost throughout the full integration that there's no business/market incentive toward it and we can't rely on the state to check and curb every business toward radical ecological change

It's easy to dream up rules and government mandates or budget items, which would be more directly interesting if we lived in an actual democracy (no matter what country on earth today) but rather we have to understand why state and business as we've enabled them to operate structurally would ever work toward those directives, and not just to an appeasingly greenwashed extent. And then think what other tools are available to us besides voting and waiting, given all that. Don't we all know devops here? Where's the structural analysis and systemically-impacting follow-up discussion? Instead people talk about the quality of individual masters and operators

Haha I guess we’re in luck. There is a global water distribution system in place for free :).

All we have to do is stop allowing industries to dump in our most important natural resource. How stupid can we be?

"Stop allowing" says a lot. An authority that dictates and enforces it? Sounds like something that loves to use its power to collude with business in every country with this society
