I pay sales tax when I buy something with money I have. That was already taxed.

Huffing and Puffing about paying taxes when you do a thing _just_ because the thing you are doing, you do with money you already paid taxes on - is a crazy idea. So crazy, nobody does it even though that happens all the time. Except, apparently, inheritance tax.

You must really hate taxes on fuel or cigarettes too, and sales tax of course.

Similarly, this:

> but you decide that you have more of a right to direct those assets for them.

Is quite the statement. That is what governments do all the time. You want to do a thing, they tell you: No, you cannot do that. If you fail to comply, we will punish you. For some countries, all the way up to and including murdering you.

Government dictates and you agree. That whole 'monopoly on violence' thing.

In this case, government has some thoughts on how you should spend your money as you are shuffling off your mortal coil. It suggests you spend some of that on general things the country as a whole wants funded. It very strongly suggests it. Insists, really. Kinda like how it insists you wear a seatbelt.
