Thanks. Seems like `org-export-visible' does exactly what I want.
I also wrote a function to copy the visible part of the region. For
those curious:
(defun copy-visible (beg end)
(interactive "r")
(let ((text "") s)
(save-excursion
(save-restriction
(narrow-to-region beg end)
(setq s (goto-char (point-min)))
(while (not (= (point) (point-max)))
(goto-char (org-find-invisible))
(setq text (concat text (buffer-substring s (point))))
(setq s (goto-char (org-find-visible))))))
(kill-new text)))

Actually (as I just found out) you can do it very easily by setting the
variable `search-invisible' no nil (found in isearch.el).

I guess it's not possible because commands work on the buffer and
usually do not know about viviblity. Maybe something like
`with-visible-buffer' could be proposed – but now with searching and
copying working, I do not really have a use case.
Thanks again.
