I am not attacking your opinion. I am just saying it is not really an opinion. It is a preference. "I am interested in rankings" or "I am NOT interested in rankings" is a preference. Of course, everybody has different preferences.
All I am trying to say is that, even if you are not interested in rankings, football depends on them (in one way or another). Every league table is a ranking, so every competition (except cup competitions) depends on a ranking (league table) to define the winner.
Luxembourg 1-1 Andorra
Luxembourg 1-0 San Marino
Andorra 1-1 San Marino
These are simple results. I am interested in results too. But in order to make sense of these results (and say a bit more about the teams), we need a ranking (or league table). If you do not wish to say anything more about the teams, or have an idea of how good they are in relation to each other, then of course you are free to just concentrate on the results and say nothing more. But to work out who gets through to the next round, we need a ranking or league table to show that Luxembourg finished first. Results on their own cannot do this.
If you are interested in who wins competitions or who qualifies for the World Cup, then you are indirectly interested in rankings (both of these rely on rankings/league tables).
When you see a fixture (for example, Belgium v Luxembourg) - you are able to predict the outcome. You will have an idea in your head about who will win the match, and you might even know the result will be 4-0 or 5-0. The reason you have this idea in your head is because you have made a mental ranking of all the teams. You know their relative strengths, because you have mentally compared historical results of teams, and your brain has worked out which teams are better than others. Everybody does it. It is very rare to watch an international match, and not have an opinion on who will win the match.
So we all use rankings, even if we don't like them. A computerised ranking is just a more accurate way of listing teams than we can do mentally (because we can't remember every single result in our head).
