Not sure how you got to the logical conclusion of my argument - my argument is that if we take DR Congo for example: they beat Cameroon and Nigeria on their way to the play-offs, both of those countries are African giants and mainstays of the World Cup.Ah, you're being very selective. Take Curacao. The major opposition in CONCACAF was cleared out of their way through automatic qualification. If the USA, Canada, and Mexico had to qualify, there is a very strong possibility - likelihood, in reality - that Curacao wouldn't have. Good luck to them for taking their chance, but the system has helped them enormously. And this is the point: the system is bloated and flawed.
And it's a facetious, if seductive, argument to say teams would have qualified "regardless" under a different system. We can't say that for sure. How do we know that the knowledge of having a guaranteed play-off berth didn't impact Sweden's approach and the results in their group? We don't.
You don't need 48 teams for "diversity". We had diversity with 16 - and certainly with 32 - and we didn't have to hugely compromise the quality and engage in gigantism to get it. As for the kids getting to see their sides on the big stage, absolutely. But you need to be worth your place on that stage. If Germany break scoring records against Curacao, I'm not sure that's doing those kids much good.
The logical conclusion of your argument is to do away with qualifying and give a ticket to everyone in the name of diversity. Infantino's eyes would light up at the prospect.
But, you're right: who cares. Nobody is forced to watch. I'll start at the knockout stage.
Curacao is another thing - but it's not like CONCACAF didn't send at least one weak team to the World Cup when it was 32 teams - Panama in 2018, Trinidad in 2006 etc.
