What's the point if your language already has hash and list immutable data types, as well as a JIT that's specifically written to optimize accesses to hashes and lists (and perhaps even transform them into destructive operations when possible)?

Because a language doesn't have a JIT, the implementation does.

Alright, what is the point of implementing zippers on top of a language implementation that already has hash and list immutable data types, as well as a JIT that's specifically written to optimize accesses to hashes and lists (and perhaps even transform them into destructive operations when possible)?

Category Theory is shit.
Topology is shit.

>as well as a JIT
Because doing half-assed things is so code monkey-like.

And code monkeys are ^ENTERPRISE!

zippers are still nice because they can be like a purely functional "mutable reference" to a deeply nested thing.
