The original statement was "A real currency is widely accepted, gold is not". The following question was "Where is gold not accepted?"
My reply of "At the supermarket" is, I think, a succinct and correct response about the basic difference between currency and valuables. My local supermarket won't take US dollars either since I'm not in the USA. You know well enough that supermarkets in the USA do take dollars, and no supermarket anywhere takes gold (if you find one, let me know what it gives as change). The point still stands. If I'm wrong, I'd appreciate more information on why along with the down-votes.
This downvote == disagreeing is so annoying, this prevents discussions.
It is one thing when someone gives an upvote for agreeing but downvotes are for insulting and off topic posts.
But it's completely irrelevant to this discussion. Context matters. And the fact that there are or not supermarkets that accept a certain currency is irrelevant to its usefulness as a reserve.
And we're talking about a country reserve, not exactly hand money.
