Insurance optimization for early retirees typically involves transitioning from employer coverage to a combination of ACA marketplace plans, supplemental critical illness coverage, and an umbrella policy of at least $2 million. For more on this topic, see Passive Income Streams.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
