Welcome to OpenStreeMap and thanks for sharing your idea about a possible improvement! However I agree with other who think it is unrealistic.
According to the OpenStreetMap stats[1] there are a little more than 10.000 "active" contributors (editing at least once a month). So splitting the world into 10.000 sections (each would have to be about 15.000 sqare kilimeters large if we only consider land) and appointing someone who is responsible for each of these sections is pointless.
So I don't think this project can be managed globally. However there are many local communities, so you may be able to join one in your area.
