While it is true that you did try to carve out a space for legitimate dependents which I agree with (although properly knowing who is legitimate and who isn't is a little fraught") you specifically haveSays the guy who claims workism involves "large inheritance taxes".
You clearly didn't read the article and still have no clue of what workism is about. And, since you are confused, you blame the author. It's as if you bought a machine and didn't even bother to read the instructions. Then you can't make it work. So you blame the engineer that created it, claiming he doesn't understand the machine he has created. That's the poor figure you are making.
Corollary 1: No Wealth Transfers, No Bequests.
Ergo inheritance taxes.
