Yes...I like that idea.
Mine would be transport them to some barren inhsopitable island in the outer hebrides.
Give them food for oh...say, a week....if they want shelter they have to build it...any other food they have to catch it, pick it or grow it.
There would be no drugs, no phones, no TV's...nothing to distract them from the long days in inhospitable terrain.
They would gain skills in self sufficiency, building, forming a community that can work together for the common good.
They would need no warders....the costs would be low and they would(I believe) never want to go back again.
And the biggest benefit would be, that once they came back into the community they might...just might, value the common goals that the rest of us work towards.
Earning an honest crust by the work of our own hands, rather than stealing their bread.

The really would be rehabilitation!
