> my goal is to never spend down my wealth

Never spend it, but you're ok with it being taken from you? You're a special case retiree if you can watch the market take half of your life savings and cheer it on. Especially with a 4% withdrawal rate, which fails a lot of 30 year backtests.

> I am withdrawing a maximum 4% a year and expect my portfolio to average >6% per year. When I die I will own the largest number of shares I ever owned in my lifetime.

A lot of successful backtests end with significantly fewer shares, too. There are no guarantees here.

There has to be some floor where you stop cheering on a market crash, because if it drops low enough for long enough then you are screwed and so are your heirs.

Be careful what you wish for.
