Taxes aren't an ethical or moral topic, they are a legal topic. If you can avoid a tax through some legal structure, you are within your rights to do so and you can't judge this as some sort of shady business. Taxes are mostly used to create incentives and collect money, if people are allowed a legal structure to avoid a probate tax, then that might be an incentive on purpose. Just because you did something to pay less taxes does not mean that you are some bad actor exploiting a loophole.
For example, taxes are only paid on profit, so companies are incentivized to spend their money and pay less in taxes. No one sees this as a legal loophole that needs to be fixed, it is very much intentional.
Also you are making the false dichotomy here of "regular people" as something different from "somewhat versed in financial entities people". That's weird.
