I have given my landlord a key recently so that he can check the smoke alarm and take the water meter reading while I'm at work. I trust that he didn't install a hidden camera even though nothing could have stopped him apart from "being a decent human being" and "not wanting to commit a crime". Not every protection needs to on a technological level. I'd rather live in a society where we have other tools available than one where I have to take each and every matter into my own hand. This is what my analogy showed.
Your analogies are really poor. Not only do you not you understand the level to which Apple or Google or your carrier can read the things you do on your devices, and how little control you have over that, but you are ignoring things like the big celebrity iCloud hacks.
For the sake of not playing an analogy war, let me just say this: if you use a modern device with OS made by Microsoft, Google or Apple (or derivative of), you are implicitly consenting to very large amount of personal data collection, which you have no control over. If you choose to trust those entities for whatever reason, thats totally fine, but your particular selection of trust isn't "correct" in the sense that it should apply to everyone, because it has no concrete objective basis. And therefore, you shouldn't base what you think the law should be on it.
