You're making an obvious strawman argument by deliberately picking an asset that isn't fungible and doesn't increase in value like everything else. Any sensible person would, at that point, sell the art, so now we can talk in sensible terms, with real fungible and taxable assets. Wealth compounds much, much faster than the tax burden grows. Someone who inherits $3 million (not much from the point of view of the very-wealthy) can live comfortably on the growth alone while still compounding their wealth further every year. The only way a wealth tax would compound faster than the wealth itself is if it is larger than the growth rate of the wealth. And since the growth of wealth (e.g. by just putting it in the stock market) has averaged at ~8-10% over the past several decades, a 1% tax is not going to eat into a person's wealth over time. It's simply going to slightly slow that growth down.
