Sounds like you have a near-identical plan to the one my wife and I have. Don't bank on the insurance company doing what they say they will, at least not without a fight. Just to throw out a random example, in the few weeks after our daughter was born we received a dozen or so letters from the insurance company all telling us the company didn't think some aspect of the childbirth care was "necessary", and that they didn't want to pay for it. Quite a shocker for us, as the birth was relatively routine, and every intervention was something the medical staff thought was necessary. In the end, after hours of phone calls, we got them to pay for most of it, but definitely not 100% of the after-deductible amount.
I hope your experience doesn't turn into mine someday. What a shady practice.
Insurers are not allowed to sell a plan that doesn't cover a long list of routine preventative care. And they're not allowed to offer deductibles greater than $2000 per person or $4000 per family.
If fails if you have an ongoing condition which costs (at negotiated rates enough that the difference in premiums between a PPO and an HSA is less than the deductible for the HSA. Personally, I don't think charging $100-200/mo in premium and expecting to pay out $500-1000/mo in existing care from day one, plus the possibility of higher costs for new conditions down the line, is a viable proposition for a private insurer. That should be paid by individuals themselves or by government (as a direct subsidy), but it's not insurance.
