I believe that the laws of your country, state, and town apply above all else, and you need weigh those repercussions on your life on your own. I would not drum for Mr. Thoreau, who did stints for tax evasion to protest the war with Spain. That was his right as it is anyone elses.
I also recognize that a thoughtfully planned and ecologically minded "crime" has no victims, and might be recognized as civic pride, civil engineering, and planet care. I know of no better way to store carbon than planting and think unplanted spaces are a waste of energy. We could be storing CO2 and biomass there. And cleaning air at the same time...
I think planting anything is an act of faith and a bit of a miracle, and approve of it over not planting things... 9 out of ten plants agree.
