It won't help them.
Firstly, gold reserves, although significant, are not unlimited. Moreover, operations related to the sovereign debt of Russia are blocked, which means that Russia can replenish gold reserves only by buying out the domestic product, but cannot buy on the foreign market.
Secondly, where will she sell gold in order to get the currency, without which, after some time, imported components and high-tech equipment for gold mining will run out and that's all
And there is nowhere to sell gold, or to China, and at a dumping price, because China wants it that way, and Russia, out of habit, will follow the order of the "big brother"!
Without international support, Russia will be doomed to failure. I can't see how backing the Ruble against Gold will have any positive effect over the country's economy, especially when it's almost impossible to do so. Putin's days are numbered, so the faster Russia changes its regime, the better it'll be for the country.
I'd say the US and its allies did a great job in trying to punish Putin's actions. But I believe that more needs to be done in order to stop the invasion for good. Once Russia backtracks, then it's possible the economy will restore itself at a slow and steady pace. Who knows what lies ahead for the Ruble before the year's end? Just my thoughts
I have repeatedly said that today's Russia with its rashist regime, world terror, both military and economic, should be perceived as a cancerous tumor on the world map. In medicine, for this class of diseases, there is only one solution - the destruction of the tumor, its metastasis (LNR, DNR, PMR, .....). Otherwise, after a while the tumor will reappear, and will be even more aggressive.
Therefore, the outcome of the meeting in Ramstein was one beautifully formulated goal - to weaken Russia to such a level that it could no longer accumulate forces sufficient to repeat the aggression against its neighbors. And when such a goal is achieved, no one will be interested in what will happen to the ruble, since it will most likely remain the currency of the most depressive territory "Moscow Republic", which for many decades will pay reparations to all the countries affected by its aggression
