Right, and if it were possible for a "good person" to prove that they have been the target of illegal surveillance, they would have standing and they could challenge the law without creating any unfortunate situations. The problem is that by the nature of surveillance and what the government does with the results (uses the tastiest bits as evidence and hides the rest), only "bad people" will ever be able to prove that they were the target of illegal surveillance. Thus the unfortunate situation.
