You clearly believe you're very objective and applying very "rational" thinking to the problem. It's about the dollar value of the income of the least well-off, so what are these stupid people even talking about inequality? Don't they realise making a poor person 10% worse off and Bezos 11% worse off reduces inequality but lowers the floor (the pedestrian argument you've made several times in this thread)?
But please consider that the problem is slightly (i.e. a lot) more complicated than you think. Economics is a very very hard discipline and perhaps more closely related to philosophy than the natural sciences. There have been countless books written on the topic of inequality by people smarter than you or me, so it's highly it's all so simple as your dismissive "just do X" line imagines it to be.
A simple, almost trivial observation: very high inequality of wealth also means very high inequality of power, meaning the rich elite can and will influence the political process to enrich themselves further at the expense of the "low percentile" less well-off, which will be denied political power. This is one example of why you should care about inequality.

Yes, and that's why I am saying that it's far from an obvious conclusion that making rich people worse off is a good thing for poor people.
And once you admit that this ain't trivial, you can look at topics like deadweight losses or tax incidence.
Different tax and redistribution system have different effects. It's not just 'more tax = more revenue to redistribute'.
For example, I actually think you can drive overall tax rates (eg as percentage of GDP) a lot higher than they are today in most countries without harming the economy, _if_ you switch to something as efficient as land value taxes for the vast majority of your government revenue (and lower other taxes). Property taxes are a second best approximation.
In contrast, capital gains taxes and income taxes are less efficient. Tariffs are even worse (by a large margin!), even if they could theoretically raise some revenue. Stamp duties or other taxes on transactions are also pretty bad. And silly things like price controls just hurt the economy without raising any revenue at all.
But that's all vastly simplified. As you suggest, there's lots of theory and practice you can investigate for the actual effects. They might also differ in different times and places.

That's why I'm saying exactly the opposite: I'm arguing against the naive 'just tax the rich'.
Wealth redistribution has this positive effect: If you take $1000 from a billionaire and give it to a very poor person, total happiness increases.
It also has a negative effect, high level of redistribution can inhibit production.
The optimal level of redistribution depends on what you're optimizing, it's usually a mix of societal happiness and some notion of fairness. (I personally would want to optimize happiness and prosperity.)
