all countries of the world build their financial policies on the same principle, focusing on the $ USD exchange rate because the world does not yet know another better system.
Everyone with a concept of a better system. Can publicize their idea and request funding to make it a reality on kickstarter. Other avenues of more discrete funding are available from many different sources. Making it easier to develop and deploy new financial concepts today, in contrast to previous eras. Free markets can then decide the value of the new system and whether to adopt it.
Formulating new ideas and formats is the easiest and least time intensive part of this process. Which is counter intuitive in terms of it also being the most neglected aspect of development and deployment inherent in financial systems.
