I disagree. Maybe you think this because you are used to another language, but once you get how var works, it's quite clear. Just because some other language do

  On the contrary, I pretty much only write JS and have for years now. And I think `var` has warped our brains, not the other way around.

  If Javascript didn't have closures, then var's scoping rules would largely be academic. But in practice, there are many cases when I have to create multiple callbacks in a loop; half the time I forget that, in Javascript, declaring a variable inside a loop does not actually create a variable local to the loop, and so have to keep debugging why all my callbacks are behaving exactly the same. The let statement appears to adopt Lua-style lexical scoping, which will be a breath of fresh air once I can rely on browser support.
