I work for a company that is helping build the digital infrastructure for drone transportation.
It is a multifaceted problem that many companies are trying to solve. Regulation from the FAA is one of the major limiting factors. Besides the mechanical issues described in other comments, being unable to fly beyond visual line of site (bvlos) is highly problematic. You need a person flying/watching the drone for its entire journey. That makes the people to drone ratio impractical.
FAA is making regulatory changes to permit bvlos that coincide with mandating remote id.
