> Because there's no limitation on pre existing conditions, it's effectively the same. You can sign up the day you get sick and have a free ride until then.
How does that work if you've suffered a catastrophic injury and you're not well enough to sign up until after you've been treated in the hospital for several days?
It's similar, but it doesn't sound like the COBRA thing, where you have the option to retroactively extend your employer's coverage, or not, for a couple of months and you can still visit the hospital the same as you always did (or not) because of the payment and notification grace period. If it turns out you didn't need the insurance, you don't need to pay for it.
