In addition to what others have said, it means some developers who were building for Android are going to stop. You can't install an app when someone is obstructed from building it in the first place.

> every Android app developer must register centrally with Google before their software can be installed on any device. Not just Play Store apps: all apps.

> Registration requires:

> Paying a fee to Google

> Agreeing to Google's Terms and Conditions

> Surrendering your government-issued identification

> Providing evidence of your private signing key

> Listing all current and all future application identifiers

Google is not an entity you can can trust with this.

From TFA:

    Delve into System Settings, find Developer Options
    Tap the build number seven times to enable Developer Mode
    Dismiss scare screens about coercion
    Enter your PIN
    Restart the device
    Wait 24 hours
    Come back, dismiss more scare screens
    Pick "allow temporarily" (7 days) or "allow indefinitely"
    Confirm, again, that you understand "the risks"

    Nine steps. A mandatory 24-hour cooling-off period. For installing 
    software on a device you own.

This isn't referring to the efforts Google has gone to try to thwart sideloading.

It is another requirement of Google's, where all developers must be registered to them and apps must be signed by them and anything that isn't will be blocked.

I wouldn't consider this "a few buttons", it's enough to turn off the less savvy users
