Ironically, weeds can be controlled through permaculture techniques and steering of the soil biology over time.

Ironically #2, healthy soil can support more vegetation due to better moisture management capability and higher productivity. What we delusional humans have come to believe is undesirable competition is actually biodiversity, a good and necessary thang.

Ironically #3, why do humans revere competition in business interactions, but strive to eliminate competition in plant communities?

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
