Yeah mate it's 150k for a patch of dirt that - if you're lucky - is less than a few km from a river and has a spattering of trees. You still need to live in a council approved dwelling too which will cost an extra 50 ~ 100k.
If you're on minimum wage paying rent then it'd take a decade or more to save even for that. Going the education route to earn more would take about as long too because of student debt + taxes + time investment for the degree.
This isn't even taking into account that house price index long term has been steadily increasing, even with a crash sometime next decade it'll be even harder to get property. So it could all take 20~30 years.
You have more freedom and choice if you just live in the woods. Especially if you can set up something with ceno, in which case you'll be set up permanently.
