Where do you think the money comes from to finance the Russian war machine? Where do you think the money will come from for Russia to replace lost/destroyed military equipment, replenish supplies of missile, bombs, shells etc.
The answer is that comes from taxes on the Russian economy and profits from state-owned enterprises. That economy is tanking - in 6 months from now, if not sooner, it will be on the verge of collapse. Unemployment will sky-rocket, inflation will be rampant, GDP will shrink massively. Closer economic ties will China will not prevent this - indeed, it's doubtful that China will want to get more involved with an economic basket-case.
This sanctions now being applied - completely unprecedented in scale and scope - will hurt Russian military power badly.
As for the laughable notion that "western media are every bit as culpable as the Russian state run media": in the West there are multiple sources of news and information, thousands of different radio and TV stations, hundreds of different newspapers and news-magazines, and generally uncensored access to the internet.
In Russia, there is now just one, monolithic source of news - the gangster-regime of Putin. No independent TV, radio or newspapers. And no free access to the internet except for those clever enough to find work-arounds via VPN.
It's bad that ordinary Russians will suffer. But there is just one man to blame for this - the dictator Putin.
