In my experience watching Argentina's matches, getting a red card like Enzo Fernandez did really messes up the whole strategy for the team. When that happens, they're forced to play with one less player, which can totally flip the game on its head. I've seen Argentina hold on pretty well sometimes, but it's always a huge challenge. As for law or government getting involved, it's not really the country's government who deals with these things. It's more like the football federation and the rules set by FIFA. The government usually stays out of it unless it turns into a massive national issue or there's something really sketchy going on. But people here talk about it for days, and everyone has an opinion! I remember last year's Copa America when a Brazilian player got carded, and it was all over the news, but it wasn't something politicians got dragged into. So yeah, red cards make life hard for the team, but it's mostly handled by sports organizations, not the actual government.
