So in lets say 10-15 years, it will be "criminal", "not eco friendly" and so to collect free water.
Or we could just not say that. I don't see any reason to "expect" water quotas.
If there is a "right" to have access to water, how far does that right go? Does my mobile home on the Moon have a right to the same access to water as you? Should society ship me water at 10k euro per kg? I see that there's apparently about 150 liters of water consumed per person in Europe. That's a 1.5 million euro per day per person right I have there. And oh look, I'm the one providing the extremely profitable shipping to my locale. How convenient.
Entitlement rights are nonsensical. It's too easy to contrive a situation where one can milk such a system for tremendous gain. Then it becomes the duty of some mealy-mouthed bureaucrat to explain why the right really isn't a right. Cue the water quotas. It's better not to waste our time with the exercise in the first place.
