I had originally figured that you believed that a government would forego its fiscal policies if a monetary crisis ensued, the general assumption for most aficionados of the gold standard (albeit one that is
thoroughly disproven by history).
The way the government forces you to make good on your tax obligations is wage garnishment: they tell your employer not to pay you but pay the government instead because you're in arrears. In general, I think you overestimate the willingness of third parties to become criminals for your sake.
