The problem with this sort of argument is that it justifies everything in the setting by its very nature. I could roleplay as Superman or get a group of friends to run around as the X-Men, because the setting does not explicitly say that they exist.
By that same token, the alternate of this argument is also true if you accept the reasoning of the first. There is nothing that explicitly says that they exist, therefore they do not.
