That has much to do with tactics, technique and superiority over the situation. Holding him in a lock simply gets replaced with being able to evade his attacks or use them to your advantage.
A lock or a hold should be the last measure, only necessary, if you are feeling unable to fend the attacker off.
Engaging in ground combat with completely covering your opponent and using your bodyweight should come absolutely last.
There is no need to give up your mobility stance and initiative if you don't feel forced to do so.
I hope you see what I said before as being relative;
Every martial arts that I know of, is under the criticism of having several training induced weaknesses.
A Ma should be able to learn a complete spectrum of techniques, such as kicking, boxing, locks, holds and ground-fighting.
I just see it that way, that the priority for me starts at the right side, that is why I focus on Karate.
It's a personal thing.
I have also taken part in a some Aikido lately, which I found pretty interesting.
I like the Japanese MA's because they are very purist and focused on the "quality" of the techniques; You need to control your entire body and can't just throw a sloppy punch once in a while, it's not really deceptive, but very direct.
