I shouldn't be given a link to disassociate a product if I don't have permissions to do so

I added a product called Notifications to a topic, but then realized that it wasn't really a product and that I should remove it. I clicked the link to do so, but apparently because it was the only topic that it was attached to, it gave me this error:

Either I should be able to remove the product so that it has no attached topics, or I shouldn't be given a link to remove a product if I actually can't.
