There is no consensus on what is "fair" to tax, you can find people arguing from 0% to 100%. And if we're talking about measures of fairness. A much better measure is something like trying to maximise the median living standard without sacrificing any one demographic.

So... where are the real resources coming from then? Because if these people aren't using them to support their living standards they must be doing something else. If we give one person enough money out of the tax pot to pay rent, that means the resources were redeployed from somewhere else that was about 1-rentworth of something.
Because I agree that the taxes aren't going to come out of the wealthy's living standards, but the implications of that in practice are not good.

Yes. Focus on outcomes.
Pick a target amount of inequity. Act to hit that goal. Adjust as needed.
For example, I advocate restoring our gini coefficient from the current 0.48 (?) back to 1970s era 0.35. People smarter than me will figure out how to best measure inequity, ideal targets, and implementation details.
Arguing about all the misc tax rates, purposefully ignoring the macro, is an obfuscation strategy to prevent taking any action at all. Straight out of the CIA's field guide on sabotage.
There is very little debate that you should be taxed proportionally to your total wealth; I.e. that the rich should pay more than the poor. In fact the only people trying to debate this are the rich who want to avoid paying back towards the society that enabled their success.

Yes, and that "somewhere else" is others' excess profit.
That excess profit comes from (a) inventing or investing capital with a return or (b) paying less for goods / labor than they can be sold for.
Capitalist profit has always been equal parts ingenuity and fucking other people over, and as most often implemented makes no discrimination between the two.
The bargain by which this has traditionally been squared is "the person who made the profit gets to keep some of it" + "they pay the rest in taxes to support the society they're successful in and depend on."
Unfortunately over the years this has continually been eroded by capital's invasion into democracy, with the express purpose of neutering the latter part of that bargain.
Those who would be hit with a wealth tax are incensed by it precisely because it would be less avoidable than the myriad of loopholes that have been engineered into income taxes.
