My gardeners don’t use leaf blowers and people are always asking what chemicals I use to keep my garden looking so lush. I don’t use any of those either; the process is called “nature”.
Look, I am as fanatical about soil biome issues as anyone that you are going to find, but your assertion is overly simplistic. If you look at a soil type map for large parts of Sili Valley, you will see big chunks labeled "Adobe". As in clay. As in it doesn't percolate. As in naturally sparse in organic matter. As in gardening contractors in Milpitas own not rent jackhammers, and it has nothing to do with the long term effects of leaf blowers.
You just have to look at the "nature strip" in front of my house compared to my neighbors on the same street. We're all on the same terrain. Mine is the only one with grass (and flowers despite people getting out of cars and treading on them).
You seem out of touch with reality (I intend this in the gentlest way possible).
