You are not correct.
At present, there are literally hundreds of millions of $$ of Russian assets held in sequestered accounts in the USA and Europe. These assets will be the first to be used to begin to pay for Ukranian reconstruction. The detailed plans for that action are certainly already made by the USA/Euro nations.
The Russian economy is pretty much already wrecked. The question of Allowing the economy to recover will be part and parcel of determining the revenue flow above and beyond the captured off shore accounts.

“In the case of unlawful seizure of state property for well-intentioned purposes, the chance of an unwanted reckoning always exists. Russia will not always be a pariah. When it returns to the fold, it will want its money back,” Stephan wrote. “Almost certainly the United States will comply with the request for repayment, which means that U.S. taxpayers will have to foot the tab for the money that went to Ukraine.”
“The U.S. track record of using Cuban and Iranian assets to pay off the holders of default judgments for human rights claims follows this pattern, with U.S. taxpayers inevitably destined to pay the compensation bill, not the perpetrators of the outrages,” he continued. “I fear the same outcome for Russian atrocities against Ukraine.”
