Good eating in seabird eggs. There's a lot of interesting modern climbing gear that you could make with quite old school manufacturing techniques (so long as you were happy to climb on static lines!) that would be quite handy for practical as well as leisure purposes.
> Can we lead a semi-rustic life? In small numbers and only for a select few. The rest of society would need to carry on as normal to sustain your semi-rustic lifestyle.
Never liked the term 'simple life'. There's a whole raft of new technical skills required to be self sufficient, and you have to work bloody hard at them... you can't relax into being a hunter-gatherer or subsistence farmer. And as you pointed out, its quite a middle class privilege these days costhere's not enough space for everyone in the UK to indulge themselves this way!
That said, given sufficient technological advances, it may become practical for many, though not most. Would it still count as the simple life when you can get your chemical synthesiser to rustle you up some antibiotics and your 3d printer to make you a new trowel?
