In the context of the comment you're replying to, none of this is reasonable, and some of it isn't even relevant. You should consider that you're forming an emotional, hostile argument.
> We, as a society, are free to decide with what's left of you and your belongings
No adjective adequately describes this belief other than "absurd".
This adds nothing to the discussion.
> Your belongings and wealth belong to your estate and as the owner of it you decide how it should be distributed.
Well, that's literally the question at hand. You don't get to just say that it is so. A dead person's wealth belonged to them, but they are dead. They can't vote, they can't apply for loans, and, the parent is arguing, they can't arbitrarily pass their money to whoever they choose. They could have, while alive, but now they are dead.
> Because it's none of your business. Why on earth are you vilifying people for wanting to pass down their hard-earned money to their children?
This is just some weird non-sequitur. No one's doing any vilifying, and Parent is arguing that it is societies business (and incidentally, given that an estate tax exists, society currently agrees with the parent poster)
