Landscapers have been a problem for me absolutely everywhere I've lived. I have two choices, rid the world of early morning landscapers or sound proof the house, starting with better windows.
Or local laws can be written and enforced about noise pollution early in the morning. Probably not that different from regulations that don't let your neighbors put a noisy windmill on their roof.
I remember a long time ago the town where my dad lived was going to build an animal shelter with an outdoor fenced in area for dogs, which would result in nonstop barking. The neighborhood got together and put a stop to that. Sounds like you would have told them all to just buy better windows and stop being victims.
Do you see no limit to the externalities which may be imposed so that some people can make more money? Landscapers would be using gas-powered nose hair trimmers if it saved them a few seconds.
Do you think that the solution to the stink from the new pig farm next door to you is appropriately handled by you installing year-round filtered air conditioning?
