Even if you somehow overcome the need for capital, how do you setup the supply chain necessary in a world where you can’t readily trade with anyone but China? Which you may not be able or doing in a month if things turn sour and China also start sanctioning.
Sure Russia has a lot of wood, but Russia doesn’t have the industrial material to transform it into furniture, and right now, Russia doesn’t have access to the high tech commodities required to build an efficient lumber industry, let alone factories to process it.
You’re right of course, this will open up for opportunities in the very long run, but it’ll be very localised opportunities that can’t take advantage of the global supply chain in a country that had an economy which was around the size of the economy of Italy before this began.
If you look at history, then you can’t really build empires in isolation. Even the current “American empire” saw a lot of its economic rise throught things like the Marshall plan, which as an example, lifted my country (Denmark) from what was basically medieval farming methods with lots and lots of manual labour to the average farmer owning tractors in less than a decade. Unless the oligarchs of Russia plan on investing basically all their national profits into building the country’s industry, then I would personally wager that these images are the last chance that a lot of Russian have to but IKEA things for a good while. It won’t stop there either, after a few years of isolation the average Russian won’t be able to buy things like coffee if the sanctions get worse.
War is hell.
