“Would I do this if search engines didn't exist”?
Would you use no follow if google didn’t exist?
That's meaningless. It's like asking "Would you install screens if you didn't have windows?" or possibly "If you worked at home, would you drive to work or ride your bike?" Or, for that matter, "Should I use Drupal, Joomla or WordPress?" The user doesn't see, doesn't know, and has no reason to care.
If a page has thousands of links, then the "nofollow" attribute will have a tiny effect on users because all those extra words in the html might add a millisecond or two to page-load time. But it's still less than the weight added by, say, a WYSIWYG editor that does everything using inline styles.
