There is nothing wrong with that because I am also an Affiliate and have launched only 1 product in which I was the 3rd partner lol. So it’s totally upon you. But there will be some people who will definitely try this because it is powerful stuff. It’s great for creating a customer base or email and list and then promoting relevant products to them.
Clickbank University is a good product that's worth the monthly membership cost of $47/month. I think that for someone looking to create and promote their own digital info product through Clickbank, this is probably going to be your best investment. If you are an “expert” in something and want to make money off of your knowledge, now's the time to start!
