did i say "anyone" should be able to change components? i didnt say anybody should be able to change components.

iphone is a device made by human, iphone is already hackable (case in point, iphone usb-c mod or headphone jack mod). it's just that apple's lawyers would very much not have that.

you just throw words like public key cryptography like it's an axiom but the tool serves its purpose as much as it's useful to us. you not caring about repairability doesn't matter, you're not apple anyway. people who got told their iphone cannot be recovered by apple but did get their data back thru 3rd party, does. (spoiler: it's because this means apple lied about their product)
