>Poof! There goes any point in investing in gold and silver.

This is not how taxes work at all, my guy. There is a thing called tax elasticity, which is a measure of the proportional change in buying/selling to change in taxation. If you want to have a good-faith discussion about taxes, at least acknowledge that these measures exist instead of pretending that any degree of taxation makes economic activity go "Poof!". It's intellectually dishonest and is not useful conversation.
