I guess the reason is "because it hasn't been implemented". There was a
suggestion recently on the emacs-devel mailing list to add a raw syntax or
regexp syntax to the Elisp reader, but nothing came of it.

In your use case, however, what I would do would be to put the call to
`regexp-opt` into my init file, not its return value. That makes it much more
readable and easier to modify if you ever need to.
