In the case of some of the lawyers I've worked with, 20 vineyards would be a conservative estimate. I'm not sure the assumption that he's consuming less is accurate though. He's consuming differently but he's still earning, he's still eating and drinking. He owns a keyboard, two ebook readers, a Mac and a rucksack full of designer clothes, a bike. The fact he's a DJ and the fact he has two ebook readers suggest that he still buys music and books (just digitally rather than physically). All of this ploughs revenue back into the economy. In addition he has no kitchen so he likely eats out more, no car so potentially uses public transport more, maybe pays for a PO Box for mail, cell phone bills are higher than landline bills. He's changed his pattern of consumption but he's not ceased it. The only way in which it doesn't scale is that he tends to sleep on friends couches. Replace this with cheap bed and breakfast accommodation and it would seem to scale fine.
