You seem to have some fundamental misunderstandings about the 4% rule. First, it uses 4% rather than 7%+ because draws go up with inflation, so you need to increase the portfolio size by 3%+ each year just to keep up.

Second, the 4% rule has about an 87% probability of success for 30 years. Extending the period to 35 or 40 years (let alone infinity) reduces that success likelihood.
