It is a nice proposal, but it's not reasonable.
In the current political climate we will never have a voluntary society. The best we can hope for it to tackle some of the worst political mistakes that we inherited from our parents and grandparents.
I am very optimistic about blockchains, I think it can eliminate a lot of corruption and make things more clean.
But even with the best efforts, it might take centuries until we really have a decent voluntary society.
It takes a lot of time and effort to build up the free market, and to defend it, since every parasite wants to cash in a buck on other people's successes.
