the mods might be ok if you remove the words 'ignorant' and 'idiot'.
I don't think I used them... Oh well, here goes.
Do you mean off-grid or just doing without mains electricity, water and sewerage?
There are plenty of examples of humankind living and thriving without what we consider in the modernized countries to be essentials. Some even in Sweden and Norway, the Sami for example. In pretty much every case I've read about or seen they:
a) Exist as family or larger groups, there are no lone wolves long term.
b) Do not completely eschew the rest of the planet, they trade with it for things which cannot be made themselves or which require more time and effort than is deemed acceptable.
c) Have been born and brought up to a life where hard work during all of their waking hours is the norm, even as children. There is no 'leisure' time other than that spent gathering food.
d) Are not usually Internet connected uber bloggers, they’re too busy working
The reason I ask about 'off grid' or just avoiding the big three (power water and waste) is I was bought a book for a birthday by my sister. It was about a chap who lived 'off grid' in a converted van (fueled by diesel - grid connected - unless sufficient waste oil from - grid connected - cafes, restaurants and fast food outlets could be scavenged) and was primarily concerned with how many amps he could eke from a solar array (manufactured in grid connected factories) to power his laptop and mobile phone (both grid connected) so he could keep his blog up to date (Internet and therefore grid connected) and sporadic forays into journalism (massively grid connected and at the heart of the geo-politic) all the while desperately searching for the next (grid connected) standpipe so he didn't run out of water. Essentially it was about as off grid as I am as I type because I'm not actually using a tap or sitting on the toilet right this very moment. You will need to be very clear about your objectives during the planning phase and be ruthless about what is actually achievable.
Near to me is an enterprising couple who have started their own off grid farm. They live in a yurt which is heated by a wood stove, they have their own coppice which they manage for firewood. Their meat comes from the animals they rear. Their water comes from a stream which crosses their land and they have composting toilet facilities which they dig and move themselves. All very off grid you'd think, but that's not how they describe themselves, they just don't have mains electricity or water. In order to supplement this (ground rent and all the other fees and costs associated with running a smallholding in the UK) they also both work full time in paid jobs and are quite possibly the busiest and most hardworking people I have ever met.
On the subject of living solely off the land here's a neat statistic for you. In the neolithic the British Isles were capable of support something less than 5,000 people who were both foraging and subsistence farming and In Namibia an area of land roughly the size of Kent will be capable of supporting about 100 bushmen - all of whom are significantly better at hunting and gathering than you or I will ever be. You'll need to factor that into how much space you're going to need to keep yourself fed and healthy without access to the bins at the back of Co-op or 7-Eleven.
Foraging for protein in Scandinavia will largely mean fishing as taking of game is, unless I am mistaken, quite tightly controlled and legislated for. Now I can fish, I'm quite good at it but if I were to use only legal methods of freshwater fishing in the UK I would likely starve well within six months and you can survive in extremis for two of those months with no food at all. The productive methods of subsistence fishing, e.g. long lining and netting, are very tightly controlled and breaking the regulations will find you fined or imprisoned. As to finding sufficient carbohydrate and vegetable matter, lots of luck with that, particularly out of the seasonal growing periods in Scandinavia as the ground frost will make digging without explosives pretty much impossible. Neat way to make mashed potatoes though if you can get the required licences for the explosives.
It’s easy to be glib and ask for peoples’ credentials regarding living off the land “have you tried it?” (your first reply in the other thread you started I believe), however, you clearly haven’t, neither have you given it sufficient thought and critical analysis.
The above may sound harsh, even rude, but it isn’t meant to be. Unless you’re brutal with yourself about the realities of what is required to live solely off the land then, at best, you’re going to have a short and deeply unpleasant trip and at worst you’re going to end up as a statistic.
With very best wishes and I hope you get to live out your dream.
