As I said before - I agree with the severe difficulties of forming nodes in the UK. And with living in what passes for the wilderness here - usually it will be too close to civilisation to get away with anything illegal (i.e. hunting, guns, bows). As for Ernesto's fighting talk - I was caught carrying a bow and arrows and charged with weapon offences. If I had claimed some inalienable right to carry weapons I would have got 4 years. Since I pleaded ignorance and forgiveness I got away with it. As nice as it sounds in theory to say 'I am a free man' it doesn't really work when everyone else is 100% behind civilisation. Laws are magic words backed up with force. The people who try to use the 'freemen on the land' defence as it's called here always lose in court. No one has ever won by it. Someone even tried to contest a parking ticket with a duel using old laws. Of course it didn't work. Your original thought of escape is probably better!
As far as I can see it there are few places that are far enough away to avoid civilisation and the law - uninhabited islands, coasts and maybe the Scottish mountains. As I've said before on here - I think the only way you can do this is sea nomadism with foraging or guerilla gardening.
Kayaks or currachs are both low tech skin-on-frame sea vessels. Gaels have built skin-on-frame boats forever - they win most Irish sail races. And they're still being built, you can learn in Ireland or figure it out from online videos. Or go to a kayak workshop next time that cool Seawolf Kayaks guy is in Europe. If travelling all the way around Scotland you can cut back through to the Atlantic from the North Sea via the Forth-and-Clyde Canal. I really don't see the point in going down through England or Wales - the sea coast is not remote enough in most places and there are not enough islands. It would have to be the Western Isles and mostly the West Coast of Scotland. Maybe trips to the Orkneys and Shetland, but I don't think it would be worth it since all of the land there is claimed and seems to be occupied.
Sea fishing is legal. Fresh water fishing usually requires a permit. Killing sea mammals is illegal I think, but if you're on an uninhabited island then just get rid of the evidence. Mussels etc are everywhere. When I was on Lewis the creels (lobster pots) were always full. There are feral sheep populations on some uninhabited islands. You can leave some more on other islands and come back to catch them later.
Plenty grows on coasts, easy enough to forage. Can plant some stuff on untended land and islands and come back later.
Well it looks like it's going to have to be some kind of tents or temporary built shelters. There are some abandoned houses on uninhabited isles. Not ideal for former civilised folk but lets be honest most of the existing HGs or herders in the north live in tents.
But last time I said all of this no one was happy with this as a solution - they didn't like this style of nomadism. I just can't see us copying the Node One way of life without buying multi-million £ estates. So I have thought of a solution since this started and this is all I can come up with with the restrictions we have in the UK - leave the civilised parts and take to the seas. For me the biggest problem would be that climate change seems to be making storms worse...but maybe profitable as wreckers. Also fuck midges.
All said, I am actually in Estonia so wouldn't be implementing any of this any time soon.
