Why should a travel cancellation insurance or a mobile phone insurance be public? You can take out an insurance for almost everything, from wedding insurances for when your spouse gets cold feed to alien abduction insurances. I don’t see why the state should be involved in that.

And of cause companies need to pay their shareholders. That’s how our economy works. Even if an insurance is state funded, it needs seed money, and that money costs interest. Either the state (i.e. you) pays the interest, or the insuree (i.e. you) pays the interest, but it has to be paid for either way.
