Well if you disable App Store you cannot re-install apps you find distracting that you have removed. I actually remove Play store from my android through the debug shell for this exact reason. And yes, it happens that when all other apps are gone, things like Ebay, Foodora, App store etc are scrolled mindlessly, it's a hierarchy of stimulation, you remove one and move on to the next best one. Congratulations that you don't have adhd, it's hell
