Enough to support our wardrobes and lifestyles. I choose my bag each day based on how it compliments my outfit. That usually means a different bag from my closet each day.
Having one bag is very doable. And some people are very happy with one bag. But I don't see any reason to limit myself. I don't own just one sweater or just one pair of slacks or just one pair of shoes. And I think most people would think something was a little odd about me if I wore the same outfit every day without change. It wouldn't be any of their business, but they'd still think I was odd. I have variety in my clothes for my mood and occasion. Same for my handbags. Specifically for me that seems to be around 30 bags.
