No capital gains tax on physical gold and silver
Physical gold and silver, if acquired possessed and subsequently sold by a physical person should not fall under any form of taxation.
As it is a storage of value and hedge against inflation. So taxing it reduces its efficacy in safeguarding wealth from economic busts, excessive money printing, and hyperinflation.
Furthermore, it makes it harder to be used as a medium of direct exchange if every time selling there is a tax due on the profits.
I would also advocate making gold and silver, non confiscateable by the government.
