It's just that people just can't deal with existence proofs. In Math people seriously tried for ~180 years to prove that you don't need a single existence proof (which notably means you can't have real numbers, or calculus) For Dark Matter we have existence proofs. It MUST exist, in some form, we just don't know what it is. It will take another century before we're at 180 years ...
