I think the biggest technical problem is that I don't think people with that kind of "net worth" really personally own what gives them that worth. There's already a lot of incentives to not have assets in your name (protecting against lawsuits, divorce, etc.), so how many of these billionaires are actually penniless in a legal sense?
Basically, you could have billions in a checking account owned by a trust, and just be an "authorized user" on a credit card that some lawyer trustee pays off from the trust. Congrats! You have no wealth to tax.
