>>My grandma kept a stash...
Interesting. I've asked my grandma how she saved given she was in the USD=42oz period but her response was we never had enough to save (postwar period really).
My mum would rather believe a nobel prize winner rather than me :) As with evertthing, views on these matters depend on ones life experience.
>> impossible to do at the volume I need
Ha! a good problem to have!
>>if trading stopped tomorrow, it could not settle and there would be huge defaults
Exactly right! but if you trade in comex futures then you are still trading in paper - albeit paper gold. When the musical chairs stop then those holding the real physical metal will be ok imho.
I don't want to be a christian missionary trying to convert but you may find the concept of freegold and the fofoa blog worth a read. In a nutshell, freegold is about thinking through the transition when the USD/paper gold market collapses and looking at what the giant players (central banks) are doing. If you subscribe to that theory then there are some good arguments why there would be no tax on gold in the future (a black market would arise to ship the gold to any region where it is not taxed). YMMV.
