He's not asking for financial advice to transport his money to the afterlife. He's specifically asking for advice as to how best set up things for the future for his children.
The "it's only money, you can't take it with you" mindset is very old and outdated and is unfortunately how millions of our population suffer from debt and have absolutely no savings and either are or will be nearly completely dependent upon the federal government through social security only. This is just simply not a healthy way to live, mentally, as a society.
But for the sake of argument sure you can't take it with you. You know what you can do? You can bless others by living more disciplined and less selfish while you're on this planet. If a person doesn't have children, you can leave it to a cause or a Church that you believe in, or anyone or anything for that matter. It's more of a legacy thing and helping others after your time here is done. Not to mention it's just a more responsible way to live and be.
