I'd say anhedonia is just a symptom of something deeper. Have you ever wondered why you're not capable of enjoying any of these things??? Is there any reason for this???
"A lot of people take for granted the pleasure they get from everyday things and some even treat it as evil. But anhedonia has opened my eyes and that is life is all about pleasure" - Well, that's debatable. I'm not entirely sure if life's all about pleasure (I'd say for some people it's all about pleasure since they've focused on this and that's questionable. They're called "hedonists"). Life's more about some other things.
"Whether you want to be successful, have a family, accomplish goals, whatever it is it all requires you to feel reward and pleasure" - That's what we've been taught since we're children, I think. Some people have other goals that not include any of the aforementioned things and, well, I think they're happy. It's much better to find your own way in life and discover what truly makes you happy. Some others think that being successful and having families will actually make them happy, but that doesn't always happen. For example, I've met highly successful people in my life and they've sacrificed everything to obtain some status and, guess what??? They're extremely miserable.
I can't say I'm 100% anhedonic, but I'm very apathetic and I've found myself trapped in a void in many times. I used to struggle against this feeling, but I stopped. The reason why I decided to embrace this void is because it gave me more strength and I could see reality from a different perspective.
Life is more rewarding when you're not hedonistic. It allows you to have a deeper understanding of things, IMHO. So, it has its own advantages.
