Why do we as a society tolerate loud landscapers?

Some municipalities have banned leaf blowers, lawn mowers, and mulchers at early morning hours. This has successfully been done in areas of Los Angeles.

Is there any logical reason to mulch trees and mow lawns and blow leaves at 8:00 AM in a residential area? Is there a logical reason to use gas powered leaf blowers EVER??

As a 21st century civilization, isn’t it time to treat loud industrial noise the same as loud “ANY” noise and force such things to occur in a narrower window later in the day?

Why do loud landscapers work from 7am to 4pm? Why not 10am to 6pm? Why do they insist on working when 30% of the population is still sleeping because they have later jobs? Why not wait until less than 5% of the population is still asleep?

Except in cases where it’s completely totally impossible?
