I don't really agree with any of your points. Wealth is a measure of your total assets at any given point in time. If you can liquidate it for cash, it's part of your wealth. Additionally, non-cash assets can be and are used as collateral all the time, so your statement about what the government can and can't do doesn't make much sense. Also, taxing the flow of money is not enough. Earning more in investments than you spend is pretty much the entirety of getting wealthy in the first place. If you only tax money flows, you're doing very little to combat inequality at a fundamental level, and at the same time leaving open giant loopholes to avoid paying taxes for things like MfA.
