You can hurt your thumb with a rubber mallet. Maybe the better metaphor would be kids' safety scissors which I guess represents the iPhone, but I'd still rather go with the Android (regular scissors) because I'm an adult and I'll take responsibility for the risks of using the more powerful tool.
I think one can still build a product that has a level of guard rails without impacting usability.
I also think iOS is more of an opinionated 'set of shears'. E.g. 'Right Hand only Scissors made from proprietary parts, made to only cut objects that 80% of scissor users need to cut' if we were to go down the road of analogies.
Funnily enough Google Android is removing the ability for unsigned non-adb APKs. I would suggest your 'regular' scissors will be slightly bluntened in the upcoming Android 16 OS release.
Not being able to run arbitrary code that Apple hasn't given me permission to run doesn't meet my standard of powerful. I won't trade my freedom for a little extra security.
