As a Finn I always find it really weird when visiting places outside Nordic Countries that for them most of the country is unaccessible.
A friend of mine went on a hiking holiday in Scotland and he told me, he just walked till he was tired, put his tent up on the next green spot and slept there.
Probably connected to the risk that squatter's rights poses to the land owner... not that pitching a tent for a night is a serious risk, but squatter's rights really encourages that kind of culture.
I am just now in a place where free camping is not allowed, but the local authorities interpret the law as: "no tents between dawn and dusk". I wish that was put into a written law.
One night of camping is not years, but squatter's rights certainly encourages land-owners to be ever-strict about visitors to their land.
That being said, there's a lot more that could be done, such as allowing kayaks into rivers and lakes without so many unreasonable limitations and/or paperwork.
There's also the water issue. If you run out of water in the west while on your hike/tramp, you're in life-threatening trouble. And there's often no cellular service.
