That is some crap that is convenient for the billionaires, we can't possibly implement any progressive tax strategy lest it degrades from a progressive tax strategy.

I'll admit the law is a slog of a read, but it is pretty clearly scoped to one time and requiring over a billion in assets. There's no open door for expanding it to broader set of people. The folks bemoaning that it's unclear on what counts as an "asset"... That point doesn't matter because the common voter doesn't have any asset that could be in that class...
