The reason why I play aram over summoner's rift

I'm not a fan of random champ select. I understand it's a fun casual game mode, not serious like ranked. But the reason I play aram despite not liking random champ select is because the map is a 1 lane map. A lot of noobs over complicate the game and make stupid decisions that cost games. What irritates me is they don't realize what actually works and what doesn't.

Multiple occasions when we get ace the team never wonders how we got that. Hello, that's like the only like the team actually grouped as 5. But then they go back to just doing their own thing and not taking advantage of their lead. People worship baron too much in league. I admit that baron is good, but not worth it if you get aced after taking baron. Nor is it worth it when you win a teamfight by getting an ace on the enemy team yet your team decides to take baron when they could have taken nexus. And then the enemy team revives and starts playing serious since they know they can lose now after losing a team fight like that, then they group and pick people off and end the game and so you lose all because your team wasted time roaming around doing stupid stuff when they could have won the game.

This is why I like aram because since it's only one lane, most people regardless of how stupid they are, will always push minions, take towers, take nexus. They don't waste time going for a random jungle camp or baron after getting an ace and you got a wave of supers already to just win the game if you go mid and take nexus with your super minions.

My question is, why are people always so stupid in summoner's rift? Why do they always make stupid decisions when they could have taken tower, dragon, inhib, nexus. But instead, one guy will always be like, "hmmm wolves look really good right now" even though a fight is breaking out at mid 4v5 and that one person could have easily come to help.
