It's possible to take a bot tower at 2:30.

That being said you need to have literally no one contesting the tower, a red buffed jungler, and a Ziggs bot at minimum.

The questions then becomes, if you fuck up so bad that you die before 2 minutes and the enemy jungler still gets a solid leash, then do you deserve to lose tower and possibly even the game? Does the enemy team deserve the tower for punishing your mistake so hard and having the coordination to get it pulled off? Not to mention they would practically have to design a composition around taking the tower. Should a tower even be able to be taken before 5 minutes, regardless of the circumstances?

The best things that you can do are to play safe early game and if you do die, get the jungler to come down and clear the wave.
