"you can actually disable the App Store! This is a marvelous win."

I thought this one was weird, personally. The App Store is among those I use least on my phone. I only open it when there is a specific new app I want to install (which is rare; I have maybe a dozen apps installed that didn't come with my phone). I easly go months without opening the App Store.

Are there people just browsing the App Store daily?

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

I think the idea is that you do not install time wasters (social media?) apps before disabling the app store. This way, even if tempted, you won't be able to doomscroll on Instagram because you cannot install it.
