1. We're not talking about what's reasonable, but what's expected.

2. This isn't like a monopoly on water supply, because the ships don't have to go this way. To make the analogy work you'd have to add something like "everybody already has a well, but supplying tap water is cheaper than using a well". In such a situation, a water company that's maximizing profits would charge just a little bit less than using a well, and while it would annoy people it wouldn't harm them.

3. The government stops water companies from gouging for the good of the citizens, which isn't a factor here.

Everybody has access to rainwater, except the people who don't. I think the analogy works quite well re point 2 (though not point 3).

We could argue about how fitting it is, but I'll just say this:

If we want to go with "everyone has suitable access to rainwater for important household use", then it changes the impact of the water company overcharging. It goes from despicable to mundane.

In the US there are extensive laws about capturing rainwater, whether you can use rain barrels, etc. although it's no longer prohibited in any state.
