I think the only way the house search warrant vs. phone search warrant comparison would work is if there was a way to know that someone used a warrant to sift through your data. You can know the police has searched your home because doing so requires physical access to the house. If there is a way to use a private key to access your data, anyone could use that key to access your data and you will never know about it. And that is really scary!

That's not necessarily true RE physical search warrants: https://en.wikipedia.org/wiki/Sneak_and_peek_warrant

But still, nothing prevents you from having cameras hidden throughout your house. There still needs to be physical access to the house. Where encrypted data can be distributed anywhere and decrypted without trace, there is only one copy of a house and it is yours.
