Who owns the sidewalk on the street?
We get free sidewalks, why can't we have automated hydroponics facilities to produce food and distribute it for free? It's technically possible, and quite simple, too.
Woah woah woah! This here is a BIG heaping serving of fail. Sidewalks are nowhere NEAR free. Sidewalks, roads, and transportation in general is usually the biggest part of a state budget, is in many states (in mine, too) is most of where your tax dollars go to. If you think automated hydroponics can be supported the same free way that sidewalks are supported, do I have a HUGE tax burden surprise for you...
Which, of course, leads to the question, do you work, pay huge taxes to build and maintain these hydroponics, and help support everyone, or do you not work, relax at home, and have others work and make money to pay taxes to support your food production? Or, I guess since there's no money or profit, do you just have faith that there will actually be people who will be boring enough to be excited by hydroponics and will work to build and maintain those machines and maintain that knowledge for nothing?
