yes it can. zero-knowledge encryption is already a thing.
> Name one web technology that is government intrusion proof.
Apparently the iPhone is. pgp encryption is another one. I'd suggest brushing up on basic security before saying things like that.
> "invasions of privacy" is not a use case.
Why not?
> By whom?
By anyone that I don't authorize. Sure, that could be my partner, coworker, any government authority, etc.
> What information are they getting from you?
Are you serious? If you don't even understand that threat model, then again, I'd suggest looking in basic security models.
> you are better defended with 2auth gmail
2auth gmail is orthogonal to the issue. That's an security method. Currently Google does that but still can grant access to anyone they want. That's a problem that 2auth doesn't address.
> not counting legal government requests
Why not? Why remove a legitimate security issue from the discussion?
> 3 cases of email data breaches that were caught
I have no idea how many have been caught, once again, that's orthogonal to the issue. How many examples doesn't matter. It's that they do have access and can do it whenever they want.
> What do you use on your life that has a lower failure rate than this?
That's a completely illogical argument. "We shouldn't ensure privacy/security because other things in life fail more often" makes no sense.
