People living in cabins is a long way from being a suburb, most people should be put off by lack of being connected to the grid too.

I can understand limits of what you can build and we do have that as well, you are completely allowed to build a cabin in your patch of woodland, up to certain size limits anyway before you do need permission. Tents are also fine. These can be left there for years just fine as well. But you can’t live in them.
