Well
Yes, the search for resources, knowledge, and adventure are all traditional motivations for exploration. Knowledge is as important if not more so in the case for Mars as indicated in my other post addressing more your title than your comments. With the deepest canyon and highest mountain in the solar system (not to mention sheer size) I think you could make a case for adventure on Mars as well. So what pray tell do you think motivates exploration?
Nice way to avoid the whole issue that you proposed a load of bull earlier. You brought the issue of resources up. It's real lame to claim their not important once your claims of resource value are cast doubt on. Is it a lawyerly or European mind set that works that way?
