  In this type of cases, yes.
  It's easy to understand with a better example:

  Suppose that you want to distribute an image so that people could only
watch it but not modify it, save it to another format, etc.
  As you can quickly deduce, this is impossible. If the user can watch the
image, he can, for example, take a screenshot of it and save it to whatever
format he likes.
  Even if he couldn't, he could decompile the program that shows the image
to see how does it decrypt the data and then do it by himself (of course this
is a lot more difficult if the program is an executable binary; but in this
case we are talking about an easy-to-understand interpreted scripting
language).
