SCOTUS disagrees with you.
And rightly so. Its more like a gift card. Don't be all butt-hurt when your Walmart hating relative gets you a Target giftcard and you can't use it at Walmart.
Actually no they didn't. They ruled the way they did because the ACA requirements didn't offer the least burdensome option, that's it, it's why they stipulated that this ruling only applied to this particular religious belief. Had the ACA not had provisions for religious non profits to avoid covering things against their beliefs, the ruling would have been different.
Unfortunately idiots such as yourself who come up with poor analogies are trying to turn this ruling into something it's not.
Your analogy would be more accurate if you were given a gift card to target for work you did but then they said you can only spend it on barbies. Just like how you are given a 401k, you can do what you want with it so long as it's in the limits of the 401k. Guess who determines those limits? The third party managing the 401k. Guess who has to follow regulations pertaining to 401ks? The third party managing it. Now apply this to health care, it's a form of compensation (you would know this if you held a job because employers always like to trot out how much you are really being paid by showing you all the benefits, like HC, they pay for) and who manages your health care? The insurance company, they are the ones who say what you can and can't do, they are the ones who are obligated to comply with regulations.
