It may sound like it makes sense, and it might be easier than picking a person (or two) to name, however there are some serious downsides to naming your estate as the beneficiary for your IRA.
An executor is the person whom you name to handle the settlement of your estate after you die, taking your estate through probate, a court-supervised process that winds up your affairs in the state where you were living at the time of your death.
The primary advantage of naming TOD beneficiaries for your accounts is that it can make the inheritance process much simpler, faster and less expensive.
