Similarly. If someone wants to go off the grid there isn't any reason to force them on to it. Ditto water supplies if they want to try something alternative. And they shouldn't have to pay for a service they aren't connected too because that would be dumb. I'd probably advocate a law that you have to disclose being unconnected to major utilities clearly, obviously and early in the process when selling or renting a house.

I don't really see why anyone should be unhappy if Sam the Solar wants to power his own house. Good luck to him. He doesn't have to pay for my electricity and I don't have to pay for his. If it is much more cost effective for him he can come do my house too. There is literally no need to force them to pay or force them to consume a service that they don't think it a good idea.

And the closer the equilibrium can be pushed to a fully private free market the more cost effective it is likely to be.
