Can't do that in a striking-only competition. Also not a good idea if you're primarily a striker and are fighting someone who is a better grappler than you.
You won't be hitting the funny bone in a striking only competition either. Additionally, just because they're a better grappler than you doesn't mean you can't catch them in a lock. When I was a white belt, I rolled with plenty of wrestlers who were better grapplers than I was. They still got caught plenty of times.
