Yes, but there's a difference in scope. Javascript cannot define the
scope of security for the core Web Stack, so to speak. These items must
be compartmentalized. The Web's architecture has loose-coupling at its
core, so compartmentalization is vital.

"The security model of the Web" has to be a composite rather than a
compound. Currently, your Javascript view is treating the Web security
model as a compound rather than composite.

A user should have the ability to save crypto data to their local OS
hosted keystore if they choose. There are no virtues in restricting that
to local browser storage, solely, at this stage in the game (browsers
with host OS interaction is already a common usage pattern). None of the
main operating systems (desktop or mobile) allow interactions with their
respective keystores without OS level authentication challenges, by
