All good ideas, except you have to unwind some regulations and hidden taxes that have driven up the cost of water.  Regarding the geardens in your backyard—25 years ago, my water bill was about $5 per month and now—even using no water, the bill is at least $70 per month,plus the cost of water! It is too much for many people and is simply not cost effective.   The water costs for planting gardens is significant if you live in a city—yes, even with water conservation drip lines, etc. Home owners associations each have individual CC&R’s.  If you buy a house that is in an HOA, you sign a legal document paper at closing in which you agree to abide by them.  You cannot just “change” that.  People have the right to live in the type of community they choose to live in.  If you want a big garden, find a place that you can have one.  Freedom includes allowing people to make choices you may not agree with.
