Back in the 1990s, during a drought (in the UK, where it rains half the fucking time), an executive of a water company told everyone they didn't need to have baths and showers, and he and his wife hadn't hadn't used theirs in weeks. Just a bowl of water, wipe yourself down. (This was technically correct, except we might also note it turns out he had also been staying over at his parents in a less water-starved region and using their shower, because that's just the sort of twat these people are.)Sounds to me like now you've named multiple distinct segments of the population that might be the subject of your description, yet you continue to view it as advice to those who can't.
The problem with this is that he's a water company boss and his company's job is to get water to people, which it was struggling to do in a country that should not really have a water shortage problem. The solutions we want to hear from him are things well in the remit of useful things water companies should do in the process of provision of water supplies like:
"We'll invest in a repairs campaign to reduce pipe leakage"
"We'll work on increasing reservoir capacity"
"We'll try to reduce waste by recycling water"
"We'll create systems to make it easier to get water from non-drought areas"
And so on.
Instead, the tool patronises us about our use of water because he and his forebears didn't get their act together, and whose only tactic for the current crisis was get the government to install a hosepipe ban, beg us to use less water, and wait and pray for rain.

And do you know what the difference is between him and the US AgSec 2025? At least he was being patronising about something that was genuinely useful, as in that situation people really did need to pitch in to conserve water. A few people extra people keeping chickens isn't even practical.
