1) The $600/month depends on how expensive the plan you had before. I've seen COBRA be as low as $350 to as high as $800, depending on the plan you had before.

2) Everything is relative. $600/month is certainly FAR FAR cheaper than the $10k/month the medicine I critically take costs. Comparable ACA plan w/o outrageous deductible is usually $700-900.

Lesson to be learned is, just because it isn't cost effective in your eyes, doesn't mean that many can't benefit from it! Feel lucky that your health needs are so basic, it almost certainly won't stay that way forever.
