They have some money, but nobody will sell to them. Slightly different situation from their money being worthless because they're outspending their ability to earn hard currency.
The self anointed "international community" is only a very small fraction of the actual world. This is typical western hubris and arrogance thinking that everyone will blindly follow them and those who don't, will powerlessly suffer the consequences of the wrath of the west. Russia has money, the world loves money, the world will sell to Russia. Not only that, but there's no shortage of western corporations busy trying to find ways to covertly sell to Russia because that's what they've done to every other pariah state. Russia will incur higher costs to acquire the things it wants but it will still be able to get them and it will often be western companies covertly doing the selling.
judging by Western MSM you see here in Europe you would think everyone in world sanctioned evil Russia while opposite is true
Yes, I think this is the key.
The difference between Russia and Argentina (where gus_massa is) is that in the latter, anyone with US dollars can buy things from/travel to abroad. Thus there is meaningful demand for dollars that contrary to the "official" exchange rate, appears in the unofficial "dolar azul" rate.
By contrast, as spaceheater said, "Since the whole world seems to hate Russians right now, I guess no point buying USD and traveling somewhere".
