you wrote > why not just make it free?? And i i've answered your question and pointed why it's impossible now. I've wrote about free food in about 100 years from now, it would imply you referred to that it this context, saying it would still have high costs in 100 years from now too (If not then why even write anything about current situation if whole talk is about future ?). Seeing how world changes, i don't think that what you wrote will be true in 100 years from now.
