Fine - I'll stipulate for sake of argument that such state laws exist. But in return I'll ask you to stipulate that of the 26 states with such laws, 21 of them provide for exactly the kind of religious exemption that Hobby Lobby is requesting now.

You're misreading the pdf. Check the 2nd page under highlights, 2nd subection, 3rd sub-subsection. Only Illinois allows the exclusion for secular entities like Hobby Lobby to not provide birth control. The exemptions provide non-secular organizations like Churches to not provide birth control on religious grounds, and the definition of non-secular organizations changes with each state (i.e. some states churches are exempt while charities and schools are forced to provide birth control, other states it's only churches and religious elementary schools, others any religious owned institution). Since Hobby Lobby isn't a religious organization or owned by a religious organization in all those states except for Illinois they're required to provide birth control.
And again, we're not talking about birth control, we're talking about a small section of birth control. If you can provide such a policy then I'm all ears but as far as I know there isn't a Health Insurance plan that only covers non-implantation birth control. There tends to be health insurance that covers birth control, and Catholic health insurance that doesn't. Health insurance that only covers non-implantation birth control as far as I know doesn't exist. That Hobby Lobby in Illinois doesn't exclude non-implantation birth control from their health care, even though by all legal definitions they could shows you what their true agenda is about.
BUT... I don't want to be bogged down in minutiae. You're wrong about the specifics but I'll go ahead and use your numbers because the numbers don't matter.
So I return to my original point - this was an easily forseeable conflict point within the ACA that its creators could and should have avoided. If you honestly think that this provision was worth risking the whole of Obamacare for, or even the possibility of being humiliated by the SCOTUS about, then you're playing for some *really* low political stakes.
In the 5 states (actually 25 or higher but we're using your incorrect numbers) with laws which require Hobby Lobby to provide birth control, Hobby Lobby has had no problems providing the birth control in question and has done so for over a decade. In over a decade it has mounted no legal challenges in those states, even though it has had many years and opportunities to do so.
In Illinois, where Hobby Lobby can legally exclude non-implantation birth control, they still continue to provide it.
I've yet to see a healthcare policy that provides birth control but doesn't provide non-implantation birth control. I'm certain you'll find plans that don't cover IUD's, or don't cover certain pills but none that don't cover non-implantation birth control. I'm not even certain what you'd call such birth control. Pro-lifers call them abortificents, but that's a medically completely different form of drug, something that causes miscarriages. And even Catholic Health care will pay for abortifacents, as long as they're not used for miscarriages (i.e. Look at your medicine cabinet and see how many drugs are not to be taken by pregnant women).
How you could predict that Hobby Lobby, who was has been fine with being forced to provide such birth control in over 25 states, who has been providing such birth control for over a decade, and when given a choice to not provide such birth control chooses to continue to provide it is a bit of a mystery. At the time it was written, the birth control section was completely non-controversial. It's only after the inclusion in Obamacare that people have decided to challenge this section.
