That's fair. I agree there is nothing like that on the market now; instead we have plans with $25k premiums and $14k out of pocket maximums. Which is less than $50k, sure, but not by much, and is a _guaranteed_ $25k cost...
We may be violently agreeing here. ;)
HSAs are from 2003 and it's overloading a reasonable definition with a new a silly one. You can see people in the mid 90's talking about high deductible and meaning something very different. ACA also capped out of pocket so you need to compare everything about a plan not just it's deductible.
PS: Find me a family plan with a 50k deductible under ACA. They used to exist.
