Then what does it matter if the signals are 2 million years old from (obviously) a far away star system? The benefit of this research is close to nil while the cost is the opportunity cost of not running something more practical. There's no basic science question to be answered with SETI, no practical policy question, no human health question, only a big "We're kinda curious to see if perhaps some alien civilization ever invented the radio and sent those waves into deep space" question. It's pointless.
