The thing to keep in mind about the requirement to have insurance is that, at least in theory, there's meant to be tax credits/assistance/exemptions for people who can't afford insurance, and the impression I got was that it would apply to fairly middle-income people, as well (unlike things like Medicaid, for which you have to be really poor to qualify).
But yes, I do wish they'd just bit the bullet and, at the very least, allowed people to buy in to Medicare/Medicaid.
