You seem to believe I argue about Germans saving water individually. I don't. Since you seem to have missed that in your rush to accuse me of "non-sequiturs", let me quote it for you:

This doesn't change that concern about water usage matters in Germany. And to spell it out for you, lest you miss it again: This is not about usage in private households. This is about commercial water usage. We're in agreement that private household changes have little influence.
That goes for your numbers as well - the 3% usage is specifically personal household usage. That isn't what I'm arguing about.
Also, you might want to correct your assumption that all unused water flows back into the ocean. Evaporation is where ~65% of the annual rain goes. (Hence my objection to "97% of it flows back into the ocean unused". It really doesn't)
And that has implications for the "renewable resource" idea, because that evaporation matters to climate overall. It's not water used by humans right now, but it's not on the table as an exploitable resource without shifting local climate either.
Then there's the fact that seasonal variability matters a lot when you talk about agriculture. The lack of spring/summer rain is a large problem, even if the net amount of rain stayed the same. (It didn't for 12 of the last 13 years, so citing 2021 is especially disingenuous)
