You are conflating the tax revenue from a wealth tax with "funding the government for a year" which is precisely a balance vs cash flow mistake like you rightfully pointed out to someone else in the thread.
So given the government will still collect taxes for every foreseeable year, I ask you, what impact would it have if we used it not to fund the government but to pay down some of the debt?
The US debt is nearly 39 trillion dollars.
Confiscating all of the assets of the nation’s billionaires wealth would yield 6-8T, depending on what kind creative accounting is done in anticipation of a wealth tax.
So yeah it would help reduce the debt slightly but doesn’t address the bigger culprit - spending and government inefficiency and bloat
