What is this going to sound like when cities have hundreds of whining drones flying around? Are we just going to have to get used to the noise pollution from the drones so people can get their coffee delivered faster?
100 years ago, you would have said "What is this going to sound like when cities have hundreds of whining cars driving around? Are we just going to have to get used to the noise pollution from the cars so people can get their crackerboxes delivered faster?"
I suggest a free-market approach: let these companies purchase the noise rights of each affected inhabitant. Then Coase can decide if having a crackerboxer two hours sooner is worth the cost.
