Great if it works for you. But welcome to the 21st century.
You see we have a thing called Individual Retirement accounts. They are by definition Individual. Then late wife had a biz so an account that was hers was appropriate. New bride came along and had of course her own account and an IRA that her son manages. While we have an account or two with joint ownership, most are simply covered with a beneficiary or POD. Sure would not want to have to try to manage a single account.
