By no means all property, and decidedly not all debt (though certainly a good chunk of it would go bye-bye), and only most laws would need to be reset. Any law which does not infringe upon another's property rights would remain respected, especially since the replacement, free market system is already partially in place. There are numerous agorist communities, at least two of which I know of in the US, and surely others elsewhere.
Are you saying you're a "hardcore statist"?
I'm a hardcore realist. If the state is the best way to deliver something, its great. If Fedex is a better option, its great too. The important thing is that the delivery get made in the best way possible.
How can you say this, then deny the reality of a better system when presented one?
