To sum up the actual questions (3 actually promotes anarchism since there would be no warlords):
2. "Who would build the X?" [Roads, hospitals, tanks]
4. "It's every man for himself; who will protect the elderly and the orphans?"
5. "Who would fix/stop the X?" [Climate, animal abuse, wars]
8. "Who would regulate the market failures?"
9. "Who would give me X?" [Welfare, SS, "free stuff"]
2. You, the taxpayer, the same way you currently build them.
4. Already answered in my previous post, first of all it isn't in our nature to harm the elderly and the orphans, second of all they would be tempted to use services to defend themselves, third is that people would be motivated to give to charity.
5. Given the free market there wouldn't be 6 corporations controlling all of the media in the U.S. like there currently is so naturally you would hear about the companies that abuse animals, the only real issue is foreign tyrannical governments invading you to give you "democracy" or some other bs reason.
8. The free market has never failed, nature has perfected it during the millions of years it existed.
9. LOL, who would take from you and give you back less you mean? Well you could pay for life insurance, health insurance etc in the company that most appeals to you.
