Well, if your house gets looted and everything is taken from you, you pretty much have to join the masses on the road to who knows where. Perhaps you can hastily garner support from neighbors you really don't know well, and hopefully they'll be someone you can trust. As said before, changing scenarios mid-emergency is something we can learn about.
Perhaps you bug out and come to a place where you can shelter in place for a while, due to being prepared and open to do things others don't think about.
Again, it's all about options. You don't have just one knife, or one medical kit, or one bug out bag do you.
No. You have several of each, just like you should have several plans to cover all bases. Can't be much clearer than that.
