It's not less honest, the federal reserve literally sets targets for inflation and publishes them. Everyone railing against fiat money while loving bitcoin have the exact same views as a government economist. The only difference is that the bitcoin/gold side keeps on trying to think of US Dollars as a store of value while the government and economists know it's a medium of exchange.
The fact that people keep money under mattresses is a failure of the educational system, not a failure of monetary policy.
