Let's be honest, the 30% cut isn't making the App Store better or safer for us customers, and this won't make it any better. But, this can definitely help scam apps scam more people, with less recourse to recover.
What lawmakers should do, is allowing customers to run arbitrary code on the devices they buy. Apple can make it that if you unlock the boot loader of your iPhone, you can no longer install iOS on it. But you are free to choose whatever other OS to load on to it, say some hypothetical Facebook OS or Fortnite OS. For anyone who likes the walled garden, nothing changes; for anyone else, you're free to do whatever you want. This also makes repurposing an "end of life" device easier, giving it a new life as something else.
