I would argue that doesn't apply. This post and whatever you call lemmy subr's is specific to the idiocy in the USA. In Europe like Canada to the best of my knowledge the public utility maintains the infrastructure up to your main. If it leaks before where you get charged, it's their problem and their pipes.
In most of the USA, their responsibility ends at your property line. Utility companies are already all privatized, electric, gas, water, and sewer. If you have an issue with a leak or distribution, they will shut you off at the property line and let you figure it out.
The added infrastructure cost for supplying water through 1 extra valve or not is paid for by the homeowner when the house was built. The labour to turn your water on and off is paid for at the time through fines and fees for disconnection and connection. There is literally no cost that they bear for your lack of water.
