I would say you are VERY close. Of course, you won’t be taking everything out of your retirement account when you retire! The goal is to make it last your lifetime, likely another 25 years after retirement.
The key point here is that you won’t be contributing to your account after you retire. So you won’t be able to “take advantage” of lower prices to buy more stocks for the next big upturn.
You will have reached a completely different stage of life — no more money coming in, no more investments being made — and suddenly that “pot” of retirement money becomes a lot more precious.
That’s why you need some “chicken money” — savings, Treasury bills, short-term safety — to let you sleep at night. And you likely need to diversify your retirement investments into more conservative (equity/income) choices now.
