Can you life without money

The knife still would have cost money, so technically you are using money :P. Unless you made it yourself of course. But with basic equipment like that you can survive in nature for quite some time here depending on the time of the year and of course you could also grow your own food and such even if you'd want. There are is like a group of monks about 50km from where I live in example and with 16 people they live from just 50 Eur a month all together, so that's barely anything. Like 25 big macs equivalent. If you'd want to live a similar lifestyle like them you can live pretty cheap, but the downside though is that you'd have to make everything you have yourself, something which most of us probably won't do unless really in need.
