Consider the idea of redesigning our economy by changing how money functions. Currently it is not an very utilitarian system for the greater part of the population and tends to serve for the benefit of a particular social class rather than as a true public resource.
Perhaps an issue with our economic system is the the full transferability of funds. Consider this, if funds were in the form of an economic voucher with limited transferability then crimes such as bribery or monetary theft become impossible. Even begging would be impossible. All forms of monetary manipulation would disappear.
I think this could have some pretty interesting implications for a free society. All it would entail is making money disappear when it spent, instead of transferring to another entity.
