His analysis is far from non-conventional. Many people have recognized and implemented the points he raises.

(1) Not all of the tradIRA account is 'your' money. Discount it by your best estimate of the the portion 'funded, owned, and due to' the government.

(2) The benefits from permanently sheltering profits from tax in a tradIRA are always exactly equal to the same benefit in a Roth. The common idea that profits in a tradIRA are 'taxed on withdrawal' is false. It confuses the account's mechanics with its benefits.

(3) The tradIRA possibly creates an additional bonus (or penalty) from withdrawal tax rates lower (or higher) than on contribution. Your strategy with retirement drawdowns is to realize a lower withdrawal tax rate (creating a larger bonus or smaller penalty) by either converting to a Roth or timing the withdrawal if the cash is needed.

(4) If your savings will not be needed for spending they are best kept to grow in the account with the smallest required minimum withdrawals.
