When is it recommended to give a Continue Anyway link

For the pages that are not mobile optimised (the operations that are done on the page should be only from a desktop. Imagine some kind of a development tool which would be used only from a desktop and almost impossible to use on a mobile), I redirect users to a standard page that says "Please use the feature on a desktop for best experience". Should this page contain a "Continue Anyway" link at the bottom? Essentially, should I give the user an option to go the page on a mobile and have a bad experience anyway? Or should I just not allow him to use? What are the cases when it is okay to give the user an option?
