The day they codify in law that public services should not make a profit, the lawsuits will begin. Those to reclassify all and sundry that we think of as public services as not being public services. A necessity argument would result. Do people need electricity, gas and municipal water treatment? No. They can live off-grid. Therefore these are not public services. Do people need public transport? No. They can walk or buy rent a car. Therefore public transport is not a public service. Do people need police, fire, medical? No. Most people can go months, years without needing any of those. Therefore they can't be public services either. etc. etc. I'm not saying I agree with any of that, but the expensive lawyers will be arguing these points and they'll continue to argue them as long as there's a profit to be made.
