The actual point is that nationalization tends to have mismanagement and shortages as an outcome, and private markets do not (at least not to the same extent). You consider NHS to be an example of a well run nationalized system, and yet the NHS deals with chronic rationing [0] [1], has queues for many things (and actually lets you pay to jump place in line) [2]. I'd hardly call that efficient or well run - instead, I'd call it symptomatic of central planning. W/ regard to people using bidets, cloth diapers, and washclothes - in a system with chronic shortages, people don't have those either. During the 90s and 00s I thought that perhaps China's simultaneous transition from poverty and shortage to (relative) wealth and abundance (which was driven by their transition from state control to capitalism) would have finally put this 'the state could eliminate shortages and give everybody everything' nonsense to rest, but it seems that people have very short memories indeed (or just weren't born yet when the major experiments in nationalization were underway).

No system is perfect. My experience with private care has been in the US, and my experience with nationalized is in Norway. I've tried to go to doctors both places with waiting lists of weeks, and the waiting is a bit longer for specialists here than there. Give and take. I'd still prefer to actually be able to get health care when i need it regardless of having the finances to do it. I actually prefer to have a mix of the two - strong national care with an option to be private.
At least it is possibly to cut back your use of toilet paper without dire consequences so long as you have clean water. It might not be pretty or wanted for most of us, but it is possible while still keeping clean. Bidets might get more popular, if available, and others would learn from the folks that use cloth diapers and real washclothes on their babies.
This situation isn't as easy to fix when you replace toilet paper with medication or health care. It isn't like one can simply make do if they are out of medicine.
