It's crazy that picking up garbage is so universally a government enforced monopoly that every county seems to have independently required it. The county runs the dump, but anyone could transport garage with minimal capital, so the garbage company doesn't have the same monopoly excuse that other utilities have, yet I can chose from three cellular phone providers but legally only one garbage pickup service can serve my address. Not only that, but if the property is occupied and service is available, I'm legally required to pay for service, whether I use it or not, and if I don't pay for it, even if I'm not using it, it'll be added to my property tax bill, and if I don't pay it there, the county will auction off my house to pay for it.
I heard that east-coast mafias had something to do with the over-the-top levels of cronyism involved, but I don't see how it's spread to every county in the west coast.
I'm in a fairly densely-populated part of the east coast and we have lots of options for trash hauling, and none of them are "official" or provided by the city.
... I do wonder about the wear-n-tear on the neighborhood roads from having like 5+x as many trash truck trips on them per week versus a municipal solution, given how fast road wear scales with axel weight. I bet it's enough to matter, which means we're all paying a hidden cost for being able to choose among trash companies. It also seems like the base costs would have to be significantly higher, given far more trucks required and way fewer pick-ups per mile driven.
