How am I giving you only partial info?
"High deductible" plans, on their own, are very unaffordable relative to only a few years ago.
Your link illustrates this even more. HSA funds can't be used for DPC monthly fees - those are out of pocket costs. You can pay service fees (for services over and above what's provided by regular DPC services) with HSA. However, you can't get money IN TO an HSA without also having a high-deductible insurance plan.
You can say the HD plan is for catastrophic situations, with DPC being day to day, but for most folks I know, especially with families, the HD plan on its own has extremely high costs, and saying "let's also subscribe to a DPC service to keep our costs down!" makes 0 sense for almost all of them.
DPC alone won't deal with "crap, I just got cancer and need $180k of treatment". "regular" insurance can deal with that, but it's still extremely expensive.
Maybe I'm missing something in what you're trying to say.
