The idea sounds nice in theory, but there is a reason people bring their car to a shop instead of changing their own oil. There are a lot of things we could/should take responsibility for directly but they are far too numerous for us to take responsibility for everyone of them. Sometimes we just have to place trust in groups we loosely vetted (if at all) and hope for the best. We all do it every day in all sorts of capacities.
To put it another way: do you think we should have the FDA? Or do you think everybody should have to test everything they eat and put on their skin?
