Incarceration: Rehabiliate and Protect? Or Punish?

By excluding uncivillized individuals from society, the average level of civility necessarily increases. Besides, who said anything about homelessness? It's litteraly impossible to be homeless in a libertarian society, since all property is owned. Homelessness = trespass.

[/ QUOTE ] I don't get this. Wouldn't this just mean that those criminals excluded from society would start living at the expense of those who are too poor or too stupid to get proper security?

Also, what would you do with those serial trespassers? Exclude them even more from society?

I only have a very vague idea about libertarianism and similar ideas, so these question are probably quite stupid, but please enlighten me.

Such anti-social individuals would simply have a tremendous incentive to just clean up their act, since it would be the least costly and least unpleasant option.

Barring that, they would probably be transported beyond the frontiers of civilized society. Perhaps there would be charitable organizations to do it, or it might be handled by insurance companies. It's impossible to say.

So I suppose the you'll a define an area as civilized society, draw a concrete border and guard it so the unwanted don't come back? Where would be the fontier on earth?
This obvioulsy cannot work..
Then why not group this unwanted pepole together in a smaller place and call it prison? Wouldn't it be much more efficient?
