Regardless of whether the virus is airborne or not, there is no need to require N95 masks everywhere or prohibit public gatherings. All exposure control interventions are ultimately futile. They can perhaps slow the spread down slightly to reduce impact on the healthcare system but we'll all eventually be exposed no matter what we do. Fortunately the vaccines are very effective at preventing deaths.
