Great article that discusses a lot of the good and bad of living an agrarian lifestyle. Simple definitely does not necessarily mean easy, but it can be rewarding by both qualities.
Something that comes to my mind is that you can definitely live a purely agrarian lifestyle like it were the 1800s or older as long as you take the lifestyle lock, stock, and barrel with it's benefits and hardships; people have been living this way for ages. But, I think what most people want are the benefits afforded by this lifestyle (the simplicity, feeling close to nature, working with your hand, etc) but to also enjoy the modern luxuries we're accustomed to (like technology, healthcare, etc), but it's really difficult to make this lifestyle support these desires.
What's worked for me is a hybrid lifestyle. I have a small house and a little land, I raise a big garden and my wife cans, so we grow most of our own food, but it's not a business, though we sometimes sell to a local restaurant and on Facebook when we have extra. We work really hard and try to be frugal, but we both also work part time jobs to make money, which gives a better return on investment for our time than we can get trying make it Simple living lifestyle support our modern needs. So we incorporate modern life employment to make simple living feasible and comfortable, but strive for simple living to make modern life minimized and tolerable.
Have a great day everyone!
