Gasoline motors are much less reliable than electric motors and require a lot more maintenance. Drones are small and cheap, so for the same amount of money you can have a lot of drones. So you should not compare load capacity for a single drone to an airplane, but instead compare load per dollar. Being big is not always an advantage. Multirotor drones have the advantage compared to planes that they drop straight down when failing, so less risk of continuing a long distance and crash in a town. Crashed drones also makes less of a mess when they do crash. FAA should adjust policy (for farming drones) due to this different risk profile.
