Dammit I had a response all typed up and fat-fingered a keyboard shortcut. WTF chrome does not even have an option to enable warning before closing a tab if you have entered content!

So yeah - the "ingredients costing more than the finished product" thing is what I meant by systematic issues. Economies of scale work great when you are "part of the economy" and terrible if you aren't, because the barrier to entry to getting enough resources to take advantage of that scale are terrible.
I'd be up for community gardens - something like a mandated 10 acres out of every single square-mile grid for community garden. Anyone can work it, get 75% of their produce, the remaining 25% goes to maintain the place. Plan it so there are rolling crops so you don't have to wait a full crop cycle to get any food.
For UBI - sounds good as long as you can find a way to do it that isn't essentially circular logic. I'd be fore this whole-hog scheme, I think I've posted it before: basically everyone keeps 50% of their income, is taxed 50% of the rest. 60% of that 50% is distributed equally to every citizen on a straight per-capita basis. The remaining is used like regular taxes. So you still have about 20% GDP as taxes. The uber-poor get 30% of per-capita income. The uber-rich get 50% of their earnings plus 30% of per-capita income. No deductions, no tax credits, nothing. All income is personal, abolish the concept of corporate income, depreciation, all that crap - just make it all zero-sum cash basis.
This incentives everyone to want to increase per-capita income. Right now the ultra rich don't care about per-capita income because they don't benefit from it. The only way a super-rich could minimize their tax burden in this proposed scheme is if everyone in the country made the same amount of money, instead of playing with accounting loopholes.
