For starters, I will surf the ocean waves and manufacture cigars (but definitelly less than 40 hours weekly) for selling and for my own consumption. Once there are more bitcoiners around me that might require services and goods from bitcoiners (a.k.a. normal people), I might start providing / producing whatever they need. But certainly less than 40 hours weekly.
Once I can secure enough land to put wild edible animals in there, enough for them to really be wild and for me to hunt some of them for food, I will do that.
Also build a nice Thai / Lankan temple at whereever I will live if there is none there yet.
I am deadly serious, always.
