For each person, there is probably an optimum number of laws. Clearly a lawless society is not the optimal situation. We need civil liberties and basic laws like you mention. Clearly a near infinite number of laws is not the optimal solution. No one could possibly keep them straight and they'll all contradict each other. Thus, somewhere in between there is an optimum.
My optimum number may vary from yours, but that isn't relevant to this thread.
To answer your question, we need to know on which side of that optimum we are currently at. To say that "more laws make a better society" is clearly false if we are already above the optimum number. To say that "more laws make a better society" is true if we are below the optimum number.
The thread question cannot be answered unequivocably (sorry I can't spell)
I personally feel we have many unnecessary laws and that they should be removed from the books. However, there are a few critical laws that should be passed to make society better. So I have to answer both yes and no to your question.
But overall, I'm in favor of fewer and more general laws and then let the courts interpret the details. For example, I perfer one reckless driving law rather than 9,999,999,999 laws stating each possible way to drive recklessly.
