Excellent point.
We have deified our rabbonim to the point where we believe they can answer every possible question or solve every possible problem. Meanwhile, they are unable to fix a leaky pipe, repair an automobile, fly an airplane, or make medical decisions. They may be well qualified to pasken halacha shailos. I found the anti-vaxx fiasco extremely disturbing, with many situations of rabbonim mixing into the subjects were they have zero training or expertise. As ling as the questions are medical, let the experts handle them. To whatever degree halacha is involved, these rabbonim need to accept the medical issue as determined by those experts, and then rule. I was terribly disappointed when rabbonim created their own halachos regarding vaccinations by disregarding the medical experts.
Even rabbonim have areas of expertise. Most can reliably pasken about fleishig-milchig issues in the kitchen, and are probably adept at Shabbos and hilchos tefila. Can your local orthodox rabbi pasken matters of constructing a mikva? Perhaps, but not necessarily so. Questions that are specialty issues belong with the experts who can be reliable to provide direction.
