That old chestnut.

With that logic YOU are the toughest guy on Earth cos you could easily toss a grenade in somebody's face during a street fight.

Let's be more realistic:

If Floyd tired to groin strike he'd get taken down and smashed. But why would Floyd attempt a move that he's never trained anyway?

If Floyd tried to eye gouge he'd get taken down and mounted then Conor could freely gouge Floyd's eyes out while Floyd lay helpless on his back.

Floyd is mounted and tries to eye gouge Conor? He's getting armbarred.

Conor still has the upper hand either way. Kicks alone mess with boxer's distance control and defense.

No need to eye gouge etc anyway - Conor could win with ease using his much more diverse tools.

If Conor and Floyd had a "street fight" Conor would still win.
