This is a straw man - nobody said ‘impervious’.
You said this:
> If you have physical access to a device, you can already tap the memory bus or countless other places
It is complete bullshit.
If it wasn’t, you’d be able to post a link to someone doing it.
If you think that is the only way into an Apple device, and that police or even nation states are now helpless against the mighty "hack resistant" iPhone, then you may be interested in this bridge I happen to have for sale.
I presume you know that isn’t an example of someone “tapping the memory bus”, which seems to be still just bullshit.
Yes, security flaws exist.
Generally we close them, not argue for abandoning security altogether as you are doing.
Police generally are helpless against the iPhone.
Nation states may well not be, but it is still going to cost them a lot.
Your argument - that because nation states can compromise the iPhone, we should make it so everyone can, seems very odd.
