No, Physical silver and SLV ETF are not the same thing.
So can I get this right, what you are saying is that people who want to buy physical silver should expect (and be happy) to pay between 10% to 35% over the spot silver price, and that this does not mean the the spot (paper) price and physical market price are decoupled.
And by inference we should just be thankfull that for the last dacade or so that we buyers of physical metals have been getting it too good by being able to purchase physical metals at single digit premiums to the spot price.
By the way I do trust you, now where can I buy all this physical silver.
