It is an alternative to what we have now. Alternatives are good. A society with no prisons means that people are more conscious than in our actual society. Prisons are not built for fun. I am sure the government spend lots of money on building them. Same thing for schools. Authorities do not build them for fun. If in a society, people are dangerous, they should go to prison. If the society, on the contrary, is well built, people are educated, then no need to build prisons or to be afraid. We fight crime because people are poor. Poverty is the actual problem of our system. Poverty and education are responsible for our problems. Do you agree?
