I've thought of this as a FIRE health insurance strategy too -- especially useful for people who are in markets which only have really crappy doctor networks on all the ACA exchange plans (cough, Chicago, cough.)
Step 1: Get a job with a decent group plan
Step 2: After a short time, if you don't "absolutely love" the job, quit and begin COBRA.
Step 3: After about a year, when there's only 6 months of COBRA left, start looking for another job with a decent group plan
Step 4: Repeat
Might be problematic ff there's a recession where jobs become really scarce again -- but 6 months is a lot of time to find a job.
