I think we're talking about two different kinds of running water...There's an entire stream of running water right next door!
I'm not saying it has to be completely modernized. But I like flush toilets and not having to go outside to get water. However if necessary I could deal with having to fill the toilet tank from a bucket, I've done that when my bathroom water lines froze. And I've been in a house that had a cistern with a hand pump at the sink. I could deal with that, especially in the short term...
