Indeed, we have been given convenience and a promise of security, but the way in which we operate is not sustainable for the vast majority of people, over a long enough timeline, imo.

As to what I'd prefer (my not having the slightest clue as to how to operate within it notwithstanding): barter and trade. Yes, I know that a lot of the things we enjoy now wouldn't be easy under such a setup, but as with all things that make life easier, there's always a cost in the end. Bargaining with the devil always seems like a great idea until you read the whole story.
