That is undeniable.
But sometimes I fear that having that much wealth concentrated in such small pieces of metal is not that kind of "distributed" security I would want to have.
Securing this metal becomes part of your very security, …
Bad security means someone (robbers, government, etc..) can very easily take those pieces of metal away from you.
And then what?

the robber part is the same for fiat, gold, bitcoin. if you depend on others to keep your valuables save, you are giving them the possibility to make a mistake or take advantage.
if you do it on your own, you are in control, but also responsible for mistakes you make. so do it right.
