Because you don't have one of these.
I've been working with him a lot, and he's getting better about being handled. He doesn't mind me looming over him like a big scary thing - couldn't care less actually. And he's fine with my hand being near him and in his enclosure, etc. But if I touch him, well ... then the poopie hits the fan. I have to make a quick grab for him or he takes off. Once he's out, he's fine so long as I keep him low to the ground, and don't try to restrain him in any way.
Poop head (Still in need of a real name)
For size reference:
And finally, how cute is this?!
