'OK, count me skeptical, why should I believe that winter is coming etc.'

Skeptical or simply ignorant of the facts?

'Central banks, which were net sellers of gold for many years, flipped to net buyers in 2010 when they reassessed their risks following the financial crisis sparked by the American mortgage meltdown. Central banks picked up the pace of their gold purchases in 2022.
That is when the West sanctioned Russia over its invasion of Ukraine. Central banks in countries that have strained relationships with the West, including China, have been shifting away from dollar-based assets into gold, which is beyond the reach of foreigners.
Others, including the National Bank of Poland, an aggressive gold buyer that on Tuesday approved another big purchase, seek to ensure the stability of their own currencies by adding assets without the same risks as sovereign debt.
“Central banks are buying gold not just purely for its price performance, but the role that it can play in foreign reserves,” said Juan Carlos Artigas, head of research for the World Gold Council. “Gold is very useful to hedge or diversify the reserves.”'

Clearly you have missed the unraveling of the US empires credibility and loss of the trade war with China.
Since you didn't notice, China now dominates global trade in manufactured goods and commodities.
China has been investing heavily in gold mining and in fact mining and refining of most high value and strategic commodities...so the World Gold Councils figures on central bank gold accumulation could be significantly lower than Chinas true gold reserves accumulation.
Investing in the mines and refining is a better investment than buying USTs.
So China now controls many strategic commodities such as refined rare earths which China is refusing to supply to any buyer who might route them to the US military.
Thus the US military is crippled- USA cannot fight any war of any scale and duration until it re establishes reliable independent supply of refined rare earths- and that will take at least a decade, probably more, maybe never due to the fucking massive cost of subsidising the refining process and the rapidly looming insolvency facing the US.
Many previous buyers of US government debt have stopped buying- the slack had been taken up by Japan and the UK, loyal subservient tribute states, but they are now facing their own insolvency.
Yes, the US empire is facing a rapid downward spiral as loss of its ability to print USD/UST debt endlessly becomes apparent. People will not take the risk anymore.
