That is not illuminating at all. Like, the author just imagines the premise and finds three ways to repeat it. There is no exploration into why people think inequality is unfair; the underlying assumption is that it is perfectly natural and trying to address it is hypocritical and harmful.

The other major assumption is that billionaires are rich because of something they did or are good at doing, better than anyone else could in their position. There is no challenge to this assumption in the text.

This belies a deep disconnect with reality, and an unwillingness to confront the idea that maybe excessive inequality is caused by too much concentrated power changing the rules to further concentrate power. Taxation is just one mechanism to combat this tendency; another way is the guillotine.
