Their take on inheritance taxes is insane, but I tend to agree that income taxes are immoral. Corporations get taxed on profits: If OkayPhysicist, Inc. spends $200 to make $300, it would be taxed some fraction of $100. Individuals, on the other hand, get taxed on revenue. It doesn't matter if it costs me $4000 in rent, groceries, transportation, etc., to make $6000, I'm getting taxed on that full $6000.
Capital gains taxes, on the other hand, are completely moral, and should be much, much higher. Capital investment benefits enormously from the State protecting their property "rights" (you don't need to hire a private army to prevent the workers from just deciding to run your factory for their own benefit, that's what the cops are for), and at a minimum the state would be justified in collecting that dividend for itself. Bootlickers and profession bootlickers (i.e., economists) would complain that a high capital gains tax disincentives investment, but as long as the value of investment is positive, that is, outpacing inflation, it makes zero sense to let your money languish in a Scrooge McDuck pile rather than get some value out of it.

So if I spend $5000 on groceries because I'm eating wagyu steak and lobster everyday, is that a fair "expense" too? You might retort that's obviously a luxury and there should be some baseline that's tax free, but then you're just describing the standard deduction.

...or they take their money elsewhere instead.
Businesses don't pay extra tax because they chose to met their needs at a greater-than-minimum cost. If my boss buys some reagents from Dave for $300 bucks instead of Bill's $200 offer, the company's not paying taxes based on a hypothetical $200 cost basis.
If we want to tax "luxury" expenses, we have excise taxes for that.
