How did we wander into the Rabbinic vs professional question here?? Was the Chazon Ish a professional? was the Brisker Rov a professional? Of course anything they said was pure Daas Torrah and nothing else. But they had the qualifications to understand the worldly stuff too better than anyone else and through the lens of true Daas Torah, and they spent their time and brainpower to be dedicated for the klal. It's not at all a given than a person who was never into these stuff, is more of a tmimusdig type, has been pretty sheltered his entire life without any engagement to tzorchei klal, should all of the sudden be making such calls at the age of 75 through filtered info to which he pays 10 seconds listening to between one rashi and the next, despite being a giant in Torah more than his peers. All the while just 10 years earlier it wasn't even a question that he isn't suited for that role. This was self understood not too long ago.
