My comment was deliberately extreme as I believed the parent comment to be. The activities/devices I mentioned can be appropriate in certain locales, and inappropriate in others.
To suggest this new vehicle has to operate at a level to not drown out birds before it can fit into society is silly. It's reasonable to place restictions on their use, e.g. you shouldn't be able to takeoff and land in quiet residential neighborhoods, instead limit them to landing on the tops of very tall buildings or transport hubs.
Also, if people are allowed to use lawnmowers and loud exhausts on motorbikes, and have been doing so for years, suggesting a new technology has to be subject to more stringent restrictions is a little unfair.
