There has been plenty written on how those things could be privatized (see the writings of Murray Rothbard and Walter Block).<p>Regarding your earlier comment about &quot;a debt to society&quot;, no one is in debt to society for those things, because no one contractually agreed to be in debt. Yes those services exist, and yes they provide real benefits, but the problem is they are not voluntary. Being in debt involuntarily is akin to slavery.<p>Now, that is the philosophical justification for one who believes in the non-agression principle. Obviously such a belief is more of a hope for a utopia which will never be realized in the foreseeable future.
