Your argument seems to mostly boil down to "Rust isn't magic", which nobody is really arguing. It does help eliminate one class of really nasty bugs, which tend to repeatedly show up in a lot of massive security hacks, and which generally everyone would like to see eliminated. Therefore: use Rust.

Comparisons to other languages like Haskell don't really work, since they don't fit in the same space nor have the same goals as Rust or C.
