Why first turret blood is a GOOD thing

When riot added first turret blood it was to fix the theme in esports of turret trading. But reports came out that it increased snowballing. "70% of people that get first turret win the game" Now think, is this BECAUSE of the first turret, or did someone get fed, destroy lane, and get first turret because of it.

While first turret is HELPFUL, it cant by itself swing a game. In fact its actually helpful, so many times my team instead of rushing to get as many kills as they can before laning ends. They rush to get first turret. Meaning most turrets are decently low by the time first turret actually gets taken since everyone is trying to get it. It also can cause teams to be much more coordinates like "bot roam up after they back and jg gank at the same time in mid and let's get ft"

Adding the first turret gets people thinking much more objectively about pushing and knocking down turrets especially in early stages of the game.
