There are only two ways to do this:

1. Him becoming destitute and poor

2. Him being dead

Neither is likely to happen anytime soon, so we’re stuck with this piece of shit for some decades longer. If the human race could collectively just ignore him, stop buying his cars and stop thinking he’s some kind of genius, then perhaps there’s a third option. But that relies on the human race having the capacity to critically think, which is even more unlikely than option #1.
