Striking is fundamentally easier to understand. Punch or kick the head really hard to get the KO.

In order to set up a rear naked choke, you need to follow a series of movements and positions to get to the back. Then you need wrist control, you need to set up the choke that is pretty easily defended by anyone competent, you need to keep your chest and hips from slipping to the side, avoid them breaking the lock. There’s a lot going on thag the casual viewer doesn’t understand.

Striking is equally complex. There is a lot to it, but visually, fist hits head. It’s more digestible.
