If we set aside 1% of the Federal Budget and used it to amass a hoard of gold and silver, over the decades we'd have enough to slowly revert back to a Precious Metals-backed currency.
If Nixon did this in 1971 when he declared our money fiat (not backed by precious metals anymore), we would have trillions in reserve already. Instead we have Fort Knox which is in practicality little more than shiny bricks in a vault.
To return to a Precious Metals (PMs) currency, we need enough of it to replace the dollar. 1% of the budget over time will add up to a lot... it'll be 100% a century later.
Is it a solution? No. But it's a step in the right direction.
