Now that's a comment I can agree with, except for the part about Ukraine being a hostile country.
The economic situation in Russia might be even more dire than your post makes it seem. Not only were wages skyrocketing due to the war and the war industry causing a labor shortage. A lot of workers apparently aren't getting paid and lots of goods have become more expensive, which should lead to a dwindling domestic demand.
The transformation from a war industry to a regular one will be painful and I dearly hope there will be a lot of pain added by making Russia pay for the damage they've done. Better make them learn the lesson now than at their next attempt.
Without the support of especially China, India and North Korea, but also parts of eastern European countries, the Russian economy would already be in shambles.
But even with money being made from exporting oil and gas, Russia's financial reserve went down a lot over the last years.
