I know you probably won't bother, so here is a brief summary of why sound money is important:
Honesty in Money - Money should serve as an honest measure and a reliable store of value.
Free Markets Need Accurate Money - Money should convey price signals with clarity so that free markets can operate efficiently.
Clear Price Signals are Key to Economic Stability - When price signals are distorted through loose monetary policy, economic resources are misallocated and financial capital is misdirected.
Integrity in Money - Sound money forges the link between effort and reward by providing a dependable store of value over time.
Ability to Plan Ahead - When money can be trusted, individuals are able to plan ahead with confidence.
Consistency in the Worth of Money Over Time - The virtue of saving goes unrewarded when purchasing power is undermined by inflation.
Asserting the Right to a Reliable Dollar - Money’s most important function is to provide a useful tool for private enterprise – not to serve as an instrument of government policy.
Limiting Government Intervention - The more power we grant to government to determine the value of money, the more helpless we become as masters of our own economic fate.
