I still hope they’ll make the rules more permissive at some point, especially as drones are integrating more and more flight automation and collision avoidance technology. Maybe certify certain drones with specific features and restrictions as being suitable for commercial usage without a license? Accidents can still happen, but... accidents can also happen with any kind of commercial activity, even without drones involved at all.
The hardest thing about getting the part 107 license might actually be getting the identification form signed, since it needs to be done by an official. If you take the exam at a flight school they'll probably offer to have a CFI do it for you (for a fee I'm sure), but if you take the exam at a non-flight-specific testing center you might have to make a trip to a FSDO or call a CFI and see if they'll do it. It would help with the accessibility of the 107 license if they got rid of the somewhat arcane proof of identity rules inherited from other pilot's licenses.
