I don’t think anyone is saying avoid taxes entirely. I honestly don’t see why money should be taxed twice. Take income tax, fine, but if I decide to save money for my descendants then let me be. On its face it’s literally just a gift.
The "double taxation" argument is nonsense. There are many taxes that apply to the same money multiple times. I have to pay income tax on the money when I get it, sales tax when I use it to buy something with it and then property tax on the thing that I bought. (Also, gifts and inheritances are taxed identically).

Wealth accumulation is inarguably a two-way street, where a well-functioning society with dependable economic infrastructure enables people to accumulate wealth and contribute to the economy which further develops that infrastructure.
