All fine and good, I hope he likes it but €10k is a lot of money to live more or less like a beggar. With €10k/y you can afford a house+food+bills in most of Europe and in many places it is way cheaper than that. So... yeah, I find it incredibly stupid.
10k Euro per year is what, 800 Euro per month? Im in the UK so I work in pounds. 800 Euro = £684.29 I guarantee you that you cannot get house, bills, and food for this amount per month. I actually think its a pretty smart and cheap way to live if you are young and can handle the requirements.
But there are like 20 other countries in Europe where it is totally possible. Don't judge everything based only on you backyard.
