I will point out that a possibility exists that, under any of several possible scenarios, the future ownership of guns in the USA could be banned or severely limited. Yes, it can happen here - as it has happened in Australia, Great Britain, and many other places. That possibility alone mitigates against considering guns as viable long-term investments. And it is foolish to believe that the Second Amendment will prevent that. Some future ultra-left Supreme Court could wipe out the Second Amendment overnight through an adverse interpretation.
