I just think its hard in principle to justify making money off an essential for life service.

There are many good arguments for nationalising an industry - particularly a natural monopoly - but I always find ‘we need it to live’ to be a weak argument. We need food to live, we need shelter, we need clothes - would you nationalise the supermarkets, the housing stock, the fashion industry? The government’s role in these things should be to make sure that the things we need to live are made available to people, but I’m relaxed about whether the provider makes a profit for their shareholder or claims a subsidy from the taxpayer - either way, we pay for it.
