If your client has a blog on their own website, they don’t have to worry about anyone closing down their content. If Google were to shut down Google+ (not likely, but always a possibility) then they would lose all of the content they had built there.
If they’re not worried about that, then they should be worried about the fact that it’s almost impossible to organize their archives in a way that people visiting their profile could see just their posts on a particular topic. That’s something that is really simple when you have a blog.
