Your argument hinges on the fact that you consider data privacy rights as "moot", "trivial" etc.. That ignores the fact that many people and the lawmakers disagree. In Germany for instance there is the fundamental right for "informelle Selbstbestimmung", the right to have governance over the information related to ones self.

Now you could certainly argue that this right is irrelevant/not needed, but you didn't bring forth arguments to this extend. Without this your argument is largely about businesses being inconvenienced (many European countries don't give businesses fundamental rights like they do for people)
