If I want to be entertained I'll watch NZ v Fra where I have no vested interest and the result is of no consequence to me.
But I am English and support England which means I do have skin in their games and the outcome of them.
And every time you put your hand in your pocket to buy a ticket or a replica shirt you are financially supporting that team. So, yes they do owe you. Unlike a club team which can be a matter of choice, your national team is also representing you.
If all you want from your rugby is to be entertained that's fine. We each take out of it what we want. But for most the results do matter especially for 'fans' which is an abbreviation for fanatics who don't tend to be neutral on results.
