Taxes are going to be a problem for any active strategy. “DON’T PANIC” from part 2 is mainly a warning about trading too often. In the U.S. at least, you can avoid some taxes by trading in a Roth IRA, but it’s problematic for early retirement. There are limits to how much you can contribute. If you mess up and bet the farm that limits how quickly it can recover. You are allowed to withdraw your contributions early without penalty (but not your returns, with a few exceptions). You also can’t trade on margin, but can use ETFs with leverage.

I came across a Mad Fientist article suggesting that a traditional IRA is worth it, even for early retirement, even if that means paying a 10% penalty on some of it. https://www.madfientist.com/how-to-access-retirement-funds-early/
