My guess is it will take a while for Insurers, Employers and individuals and org's such as churches ( Yes I believe they can form groups) to rap their heads around these "Association Health Plans (AHPs)".
When they do and realize, holy smokes we can link up with like groups and have huge leverage via purchasing power of large groups, Katie bar the door, that when the changes will hit.
the million dollar question is when do they go back and take a stab at undoing Obamacare and make Direct Primary Care universally accepted, it isn't currently, only amongst some large group plans. That is the game changer IMHO and I don't know who will be Dr Tom Price's replacement and can they do it with the HHS "Administrator Shall" powers in Obamacare, which to me is brilliant, use their own devices against their legislative fiat.
