Why in some countries buying silver is so hard?

[speeder]

I am from Brazil...

Here I cannot find anyone selling silver, and when I tried to buy silver form Bitcoiners that were professional silver dealers, they all warned me of crazy custom taxes here.

But finding gold here is much easier, although seemly also highly regulated, you have to buy the bars from major banks, and they come inside some plastic casing, and you are not supposed to meddle with the bars until you sell them back (to the bank), it looks like the government decided to use gold as a form of savings account, where you hold the physical gold, but in a more or less illusionary manner, yes, the gold is there, if you melt it ,you will see it is real gold, but it is inside a plastic shell that is not your property...

And silver...

Seriously, where I can buy some silver?
