The garden! The garden! It’s sad that urban areas are not set up so people may have garden space to do the most basic been-done-for-10,000-years feed themselves without regard to a for profit grocery store. Part of some people’s desire to have a garden on a seastead is because of this “food insecurity” on land where they are now. If you have no money, people will stand by and watch you starve. It’s not usually a culture or a choice to starve. Even if on a boat with a net and a longline, your fridge may die, the fish may not be biting, you may be out of bait, the water too polluted, but you can still eat well enough with a garden on board. To me, if you have a roof, you should have some form of solar assisted power, water treatment, or food growing up there. Else you are wasting money merely to create shade. In my opinion. Caveats may happen. Batteries not included. Your mileage may differ.
PS: I lived in my car for years too, not by choice. Mostly because of “policy”: $2000 down, it’s upstairs, no parking within 1/2 mile, 30" skinny doorways, we don’t talk to people like you, the real estate office is not accessable, and the real head-scratcher was “we don’t rent our apartments to homeless people”.
PPS: I live in an area where gardens are so white trash. And solar panels are stealing from the power company and make you immoral. And having a burn barrel smoking 24-7 is the norm.
PPPS: So i don’t know of a place i can afford to live where humans won’t cause trouble, unless it’s on a boat such that they don’t know where i am.
